The next generation COB LED?   (Radical new style of bare LED chip.)
 
20:55
I'm not sure how I missed this. It's possibly because it's a secret that has been hiding underneath a phosphor loaded gel out of sight. Could this be the answer to the bond-wire problems in the early low voltage 20-100W LED modules? It's a new package of bare LED dice/chip that can literally be soldered onto a PCB as if it was a standard surface mount component. Just a very-very small one. It makes me wonder how they pick and place these and check the orientation before placing on the PCB. I guess the bare chip could be dabbed across some tiny contact pads to check if it emits light. When I tested this COB (Chip On Board) array with very limited current the LEDs all glowed uniformly, even at the point they were all just barely visible. The same can't be said for the older style low voltage module I also show in the video. It had a high number of defective LEDs exhibiting damage in the form of parallel resistance suggesting film damage. Possibly caused by the wire bonding process. When powered the older module would also extinguish whole rows of LEDs when pressure was applied to the busbars at the end of each series string. Just for fun I tested this LED with a 470nF capacitor in series to act as an external current limiter. The power indicated by the Hopi was 3.4W and the module put out a useful amount of light without getting warm, and would probably last decades with that very low current. Could be a useful way to switch a floodlight made with one of these between normal power and a low level ambient output. The contact block on the PCB which was clearly not bear-proof looks more like a push-in style for solid core wires. My attempt to treat it like a Wago terminal and "open the spring loaded contacts" just forced the folded contact strip apart and broke the little tab that is just a wedge that is supposed to part the sides just enough to get a wire back out again. I wonder how reliable this new type of LED panel will be over time. It's a foregone conclusion that the manufacturers will be pushing everything to its limits so thermal stresses may be an issue. As with all this style of driverless, or more accurately DOB (Driver On Board) LED module there is no smoothing. So the flicker at 100/120Hz is strong. They could design a COB to take an external capacitor or externally rectified and smoothed supply if they increased the number of LEDs in series to accommodate the higher smoothed voltage while still allowing a margin to drop across the active current limiting circuitry. I'm guessing that the new LED chips may be limited to Gallium Nitride technology at the moment, hence the use of phosphor to make the red and yellow COBs. The green ones seem to be available either with phosphor loaded gel or as bare green chips. Note that if converting a 110V COB to 220V by swapping the links the current will still be set higher, so the parallel resistor cluster may need to be adjusted. If converting a 220V COB to 110V the current will be lower than a stock 110V COB.

COB style 3W LED light teardown.
 
02:37
This is a fast teardown of a COB (Chip On Board) style LED lamp. Unlike the earlier LED lamps that used pre-packaged power LEDs mounted on aluminium core PCBs, these ones mount the bare chips directly on the PCB and then cover them with a protective gel with phosphor in it if required. This improves thermal conduction to the main heatsink and also cuts down the cost for the manufacturers dramatically. This technique allows them to create custom shaped power-LED panels and wire them in series/parallel arrays as required. This partticular lamp was interesting in that it used a traditionally shaped Luxeon Star type base. Probably to facilitate use of an existing heatsink style pre-drilled for that package. The power supply is sleeved in nice thick heatshrink in this light which is nice. I wouldn't rely on these little supplies being properly isolated from the mains due to the way their little transformers are wound with primary and secondary windings in close contact. Likewise the LED PCB is closely coupled to the aluminium heatsink with screws that overlap the PCB tracks. So I'd always treat the exposed metal of LED lamps as being potentially live as a precaution. Very smart looking lamp with a nice wide beam of useful light. In open air the metal does get hot to the touch. I sometimes wonder if the manufacturers are compromising LED life with undersized heatsinks.

The biggest LED COB panel yet!  Voltage/current tests.
 
14:04
This thing is huge and bright. It runs at around 12V, but has no integrated current regulation. This means that if connected directly in a vehicle application the current could be very high and the voltage drop across the supply cable will be a factor in limiting the current. The circuitry is basically four large parallel arrays of LEDs connected in series to make up roughly 12V combined forward voltage. I did some voltage/current tests as follows:- 10V 7mA 70mW 10.5V 170mA 1.8W 11V 790mA 8.7W 11.5V 1.72A 19.8W 12V 2.85A 34W 12.5V 4.2A 52W 12.8V 5.2A 66W Current Limit of bench supply. As you can see form the voltage to current ratio the current increases significantly with a small voltage change. A typical eBay search for this might be:- https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313.TR0.TRC0.H0.X70w+led+cob+panel+12v.TRS1&_nkw=70w+led+cob+panel+12v&_sacat=0&LH_TitleDesc=0&_sop=15&_osacat=0&_odkw=70w+led+cob+panel&LH_BIN=1&LH_TitleDesc=0 If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

A look at some LED COB light strips for cars / automobiles.
 
04:54
This is one of a variety of LED panels using COB (Chip On Board) mounting of LED arrays. In this case the unit is designed to directly operate on 12V by using four parallel groups of LEDs wired in series to give a combined forward voltage of 12V (4 times the typical 3V forward voltage.) Unfortunately this unit would pass an extremely high amount of current if used in a vehicle, as the alternator charging voltage is higher than 12V and while the panel drew about 350mA at 12V (4W) it increased to about 1 Amp at 14V (14W) and that results in the metal backplate getting very hot quickly. The inclusion of self adhesive foam strips to attach the lights to a surface doesn't help much as the foam would provide extra thermal insulation.

Massive ebay COB LED Grow light test
 
05:46
https://www.migrolight.com I bought a '12V 70W 7,000LM LED Panel Strip COB Light Lamp' from Ebay and tested to see if it suitable as a grow light. It's well made. The aluminium board is thick and solid and all 336 of the LED's are well matched so it is likely to be reliable to run at the correct load. The data sheet says 12V DC and 70 watts but at 12V it draws over 4 Amps and runs very hot. At 11.5V DC and 2.5 Amps it runs pretty cool. We tested it at this wattage (33.5 watts including the LED driver). The light outputs 44 PPFD at 9 cm from the canopy over 2ft x 2ft or 60cm x 60cm. The PPFD per watt is 1.42. You would need at least 4 to cover a 60cm x 60cm grow space. Thats €40 for 4 + €10 postage = €50 The driver, wiring, plugs etc = €50 Total €100 for a 100W, 1.4 PPFD per Watt light. Not really worth it, better to buy a MARs reflector or equivalent. However if you have a 12V power supply current limited to 2.5 Amps this will work perfectly. Thats what I am going to do with it and use it as a seedling lamp.

The shocking truth about cheap LED "corn cob" lamps
 
09:40
NOTE: CE does NOT mean China Export, it's just a mis-spaced CE logo (just like the one on the back of an Xbox 360). https://en.wikipedia.org/wiki/CE_marking#China_Export Comments mentioning China Export will be marked as spam automatically, because it's horseshit. Commenters trying to use alternative characters to bypass the spam filter get muted from the entire channel. Based on feedback comments on my earlier video and a request from the folks at http://www.avforums.com/, this is a shorter test on a range of "corn cob" LED lamps available on eBay and Amazon. If you're thinking of buying cheap LED lamps, whether it be online or from the local market, this video is for you! Of the six "corn cob" style LED lamps tested here, only ONE could be considered safe to use. Watch the video, know what to look for in a safe bulb and know the risks associated with the dangerous ones! Some details left out of the video: At 50mA-100mA, ventricular fibrillation (very rapid uncoordinated contraction of the ventricles of the heart) is possible. Hand-to-hand body resistance of an adult lies between 1,000 and 4,000 ohms, depending on moisture, muscular structure and voltage. The average value is 2,100 ohms at 240V AC. (source: Basic Industrial Electricity: A Training and Maintenance Manual, Kenneth G. Oliver, p156) If your resistance at the lower end of the scale the current will be higher and the 100-200mA range is where you're at highest risk of fibrillation (and CPR won't fix fibrillation, you need a defibrillator for that). Apologies if some of it sounds a bit scripted, that's because it IS scripted to stop me rambling quite as much as usual, I'm trying to strike a balance between brevity and detail here, and it's tricky! If you want more information about what's inside the lamps, please take a look at my earlier video:- https://www.youtube.com/watch?v=n3ci4... Not interested in corn cob lamps? Mains LED spotlamps are just as bad! Check out Julian Ilett's video:- https://www.youtube.com/watch?v=keaE7...

Car LED globe comparison. w5w, t10, cob, smd, cree
 
02:03
Ebay has plenty of these dusty nasty cheap led's, but which one to buy? This video is a comparison of output, use as a guide for your own judgement. There are probable inconsistencies with kelvin but who really cares. Note that the SMD's are prone to go an ice blue over time, then dim and flicker until they decide they don't want to be part of this earth anymore. I would avoid any SMD style, and opt for the COB style globes. They appear more solidly built. Note that I have h10 COB style LED fog lights also. For the DRL , I went for the highest wattage + lumen range as the MS3 driving light housing requires quite a beefy globe to reflect the whole DRL paths.

It's the same led, but all you have to do is insert the +/- wires directly into the cob. The regular Vero uses molex wiring harnesses, and they are a joke. They take forever to wire and end up falling out of the socket half the time! 2. Design for canopy coverage, not just power. More LEDs at lower power are more efficient and give better coverage. For this reason, I've since redesigned this light by further spacing out the Vero 18s, then adding numerous Vero 10s at 500ma on 2.079" heatsinks from heatsinkusa. 3. Use the thicker 3/4" angled aluminum stock for the frame and get different heatsinks. I did what I did because the mechatronix heatsinks don't have holes on the sides for mounting. For more plug and play, use the sst120 heatsink from northern grow lights or cutter (expensive/easy option). Or (for the cheaper/more diy option), go with heatsinks from heatsinkusa. Growmau5 has a video on how to calculate what you need. HSUSA is the route I'd take because I'm cheap and don't mind drilling holes... A couple more things I've gathered from using LEDs. 1. I don't always run the lights on maximum power. More doesn't always equal better. Since I don't have a par meter, I generally shoot for: 15-25watts/SQ foot in early to mid veg, 25-30w/SQ ft late veg to early flower, and 35-40w/square foot mid to late flower. Anything more than 40w and plants need supplemental co2, precise environment control and watering/nutrient needs increase. Temp (even with LEDs) can become an issue. So keep it simple and start small until you really dial in your environment and learn the plants needs. 2. Light spacing is between 16-24" from canopy. 3. Buy the largest grow tent you can get away with. It makes controlling the environment much easier and provides room to grow in. Plants generally do better when temps/humidity aren't constantly fluctuating. Plus I hate cramped spaces. 4. I've changed my grow style to maximize canopy surface area. You can use SOG, SCROG or even both. SOG (sea of green) is a lot of smaller plants spaced close together, flowered young. Right now I use SCROG (screen of green) for fewer, but larger plants because I can legally only have 6 plants growing at a time. I top once or twice early, then selectively prune the lowest/least productive branches through late veg. After 5-8 weeks veg I switch to flower, then begin training the branches through 3" trellis netting to create a nice even canopy. Less pruning is better, and there's much debate about doing it at all, as it can stress plants, but I find it easier to water and maintain adequate airflow in my grow space. Just make sure you're not doing any pruning after week 2 or 3 of flowering at the very latest. 4. Look into leaf surface temperature and VPD to dial in your plants environment. I had so many issues disappear once I figured this out. Last, but not least! Remember that most of what you read on forums or see in videos is anecdotal (that goes for me too, I guess). Just keep growing, taking notes and learning from your plants! For more information on how I built this I'd suggest you watch the Growmau5 diy led videos, or drop me a questions in the comments. If anyone is interested I can drop part #s and suppliers I used as well. Thanks for watching!

Apollo UFO vs HHE COB: LED Grow Light Experiment (Hydroponic Lettuce)
 
08:56
I've been using my Apollo Horticulture UFO SMD light for nearly a year now. After acquiring my latest LED grow light by HHE, I saw an opportunity to run some side-by-side comparisons. The HHE COB (84w) light had been labelled as "200w" while the Apollo (109w) is still labelled as "180w". Using bogus wattages creates a certain expectation on the part of a consumer. If the HHE is touted as 200w then the performance should be 11% greater than a 180w model. But is this the case? I devised a simple, unbiased experiment to test these grow lights against each other. Planning this experiment sparked a renewed interest in hydroponics, leading me to the "Kratky" method. Here are the basic parameters for this experiment: - HHE 64x3w COB (84w) vs Apollo 60x3w (109w) SMD UFO - 9 Lettuce Plants each (Tom Thumb) - Kratky's Method of Hydroponic (non-circulating) - Identical Nutrient Solution - 17 Hour Light Cycle. - Grow Area: 24" x 24" - Distance: 15" Apollo Horticulture 180W LED UFO Grow Light (GL60LED): Amazon: https://amzn.to/2Ga7cXa HHE 64x3w COB LED Grow Light (B01080K8TE): Amazon: http://bit.ly/1LHUlZj The Apollo Horticulture LED light draws 30% more power. But it uses the SMD construction method for its LEDs, rather than the "more efficient" COB style. The spectrum of each light is clearly very different. But which light will have the best lettuce production? You can see them growing side-by-side in a time lapse video which spans the course of 23 days. We have hydroponic lettuce. We have LED grow lights. We have time lapse. There's a lot going on here! #IndoorGrowing #UrbanGardening #ArtificialLighting #Hydroponics #GrowYourOwn #LEDlighting ••••••••••••••••••••• SUPPORT: ••••••••••••••••••••• W E B ➝ https://albopepper.com F B ➝ https://www.facebook.com/albopepper I G ➝ https://www.instagram.com/albopepper T E E S ➝ https://shop.spreadshirt.com/albopepper/ •••••••••••••••••••••
