CHANZON High Power Led Chip 100W White 6000K - 6500K

I have been using 3 of these (the 100w full spectrum grow light cobs) for about 4 years now. Running them at FULL brightness with proper cooling for either a 12 or 24 hour light cycle, I have found no dimming or burnout. These last a long time. Mine are all mounted on old CPU coolers, powered by computer power supplies and boost modules with good current limiting. My black sapote trees grew 3 feet over the winter which I thought was impossible. Will be ordering many more!

At first I was worried that the Blue LED didn't have any actual LED Chiplets, especially at that price, but it turned out to be perfectly normal. The 730nm Far RED LED met expectations perfectly. I took a spectrum of the light output at 10mA/15V (the dimmest it would go) and the wavelength accuracy was excellent. It worked perfectly installed on https://www.amazon.com/dp/B01D1LD68C heat sink base, the hard part as always was soldering bare wires to the power pads. Be sure to keep it from having a large ball of solder (will block the optics) and make sure the solder actual wets the power pad. It takes a lot more heat and time than most people expect.

Works great, replaced a 200 watt full spectrum chip in my Failed Apollo light fixture with this 100 watt 6500k chip. Plants are happy using on the "VEG" side so full spectrum is not needed. The old chip had two drivers powering it, 1 for each side of the chip. Used 1 driver to power this chip works just fine still super bright, and have an extra driver for later use. the 200 watt chip are a lot more expensive so this is a great alternative. Used some thermal paste in between the chip and heat sink. soldered the old wire with the old "clips" attached for easy hookup! have been in use for 2 weeks and still works Great. Plant is getting huge under this bulb/Chip! Update: 1/13/20 been using this bulb off and on now for almost 3 years and still going strong but it does blink on and off for a coulple minutes when first turned on, looks like all 100 diodes are lit still hard to see its so blinding probally a driver issue not the bulb been doing that for months now but keeps going. 5000k to 6500k works great for growing plants much brighter than the T5 fixture with 6500k bulbs next to it. The sun is 5000k so these are close. full spectrum or 3500k or lower for flowering plants.

I bought a 4k LED to use as a grow light, but I'm still working out the design and building everything. But I just wanted to quickly add a review. So far, I'm very happy with the light. Excellent price is given how much light it puts out. I don't have a PAR meter, only a Lumens meter. This LED at 10" distance is 4-5 times brighter than the CFL bulb it's replacing (2000+ Lumens vs 250). Sweet! I am also able to pull nearly 100W out of the LED. At 3 amps, I'm hitting 32 volts which I mathed out and if I recall correctly- that's about 97 watts. The specs on Amazon say 3amp max, but I saw Chanzon say it can go to 3.5amps. So I could go even brighter, and squeeze out those last few watts, but I'm happy with where it's at. I wasn't expecting to run more than 70watts out of this LED so 96/97 watts is fantastic. Once I get everything set up, I'll probably be in for another 2-3 LEDs! My setup: $6 - Xbox 360 Power Supply - 12v / 12-14amps $5 - Boost Converter - Converts 12v to 32v $0 - Intel i7 CPU Cooler $0 - 120mm Corsair Case fan (cooling the Boost Converter) With parts laying around already, this has been a super affordable build with excellent output.

This is an extremely bright IR LED in the 850nm wavelength. When working with this LED I highly recommend wearing a pair of laser safety glasses or goggles that will adsorb 850nm light. This LED will give you an eye strain headache in a matter of minutes. https://www.amazon.com/dp/B00UIYKI28?psc=1&ref=ppx_yo2_dt_b_product_details . This LED also gets extremely HOT and MUST be mounted to a good heat sink with a fan. I'm using this LED for security camera lighting. and will be mounted outside in an enclosure (old camera housing) The enclosure will be sealed off so water does not enter. I decided to cool this LED with a water cooling system. LED stays cool at 3 amp current. I would have given this LED 5 stars. But I cant figure out how they came up with a 100 watt rating. I did some independent testing. Vfd = 14vdc. Ifd = 3A. Pd = Vfd * Ifd = 42 watts. Still a very bright IR LED. UPDATE: 9/24/2021. I have been using this LED for over 30 days and no issues with it. I am keeping it very cool using a water cooling system. The cooling system is working so good that I decided to pump the current up by 50%. I'm now pushing 4.5 amps. been over a week so far so good. I may design an LED driver circuit determined by temperature of the chip. I am currently driving the LED chip with a 15 volt DC power supply with a series resistor. VERY IMPORTANT!! You must keep this LED cool!! Have any questions? email me at esdpain at yahoo dot com.

Used these to replace some very old chips that were partially failing. Great replacement part!

Mi producto llego tal como esperaba excelente calidad

I have several 50W versions from this same vendor which when I set a bench power supply to a modest output of about 30W (29v @ 1A) it delivers 10k LUX measured at a fixed distance (about 10 inches). All good and I was happy with the performance of that 50W LED. BUT....when i switch to this 100W LED I have to supply over twice the power (over 70W) just to achieve the same 10k LUX at the same distance. Said differently, if I supply the 50W or 100W chips the same 30W of power, the 100W LED is much less than half the LUX at the same measured distance. It makes no sense, over twice the power (and the extra heat need to go somewhere) just to achieve the same LUX as the 50W version. Shame...I'd buy more if the LUX/watt was even close to the 50W version.

These are the best COB's at this price point in my opinion. I thoroughly tested all my COB's at low voltage (About 25V) All the LED's on all 4 of my chips light up at exactly the same voltage. On 100W COB's 10 rows of 10 LED's. That's 400 individual LED's working exactly as expected! These things are impressive. I would love to see someone with a proper light meter compare these to the CREE's and the Vero29's If you want good LED's without spending £20+ a chip these are amazing for the cost. They seem amazingly bright to me but it is hard to tell without a PAR meter or the like DO NOT get the cheapo ones they are not worth the plastic they are moulded in...

good quality , very useful for night light..

10年つかっていたやつが 光らなくなっりましたが これに交換して 復活しました。

worked great for my application.

The LEDs seem very well balanced, and all start glowing at the same time when I slowly ramp up the current, and I'm very impressed by the light output this thing produces. The back is also coupled quite well to the LEDs thermally and allows me to pull the heat out of it pretty effectively. You definitely don't want to run this without a good heatsink and when it's on you should absolutely not look at the front of it.
