Introduction 100W LED 2 People Made This Project! Recommendations21 Commentsno need to regulate current?If you want to get the full operating power from one of these LEDs, you need a constant current driver instead onf a constant voltage one. Something like this is perfect for driving LEDs as it has such a facility for driving them at their peak current.

I'm also trying to hook up blue 12v led lights, so i don't want to stress the battery with 4 different circuits running through it. 1system/2charge the lithium-ION/3100w chip step down/412v led step downHello, im building a 100 watt maybe 200 flashlight with 1 or 2 100 watt led chips. My Question would it be better to power it with one 12volt battery or two 12volt 5ah batteries in series equaling 24volts 5ah? Please any I connect 3 100watts chip to one 600watts invertordoes anyone know where to get lenses from? 44mm Lens + 50mm Reflector Collimator Base Housing + Fixed bracket for 100W LED Light Lamp $ am making a 100 watt LED light coming from a 600 watt booster. I would like to run two separate lights for two different people with on/off capabilities. Setup 12v mower bat》 inline fuse》600w booster》2 on/off push buttons with 2100w led lights on 2 separate peoples hand. Flounder lights i have the single one working, can i get 2 to work off one booster or do i have to change the volt pot to work at double and turn them on at the same time or _____?I can't see point 3 in image/video. Is that circuit really needful?I followed the link, but I have no idea which transistor i need to replicate schema. Can someone help me?I build a 100 W LED too. Maybe some hints for you made one of these with a different step-up regulator and have drawn up a schematic of it if anyone is interested in seeing more details doesn't put out 100W made the circuit and I encountered a supplied from a source computer and functioned properly, but when I powered by a car battery to light it i've tried to use a 50w led with the same driver you have. but the problem is whenever I try to power it with 12V supply, a hissing sound comes out and i only get 27V at the output with load and around 35V without load means without the LED. Is it normal or do I have a faulty driver? have had the same problem. I found that the gauge wire i was using was either too small or too long causing to great of a voltage drop through it from the battery to the boost converter. once the input voltage dropped to about 9-10v the converter would begin to hiss and the led would flicker. So check the input voltage to the converter at the converter and that should solve the do i really need a current limiter to drive the LED and if yes, what transistors/resistors will I need?32V, 3A and do I need PNP or NPN transistors?I think the step up converter is current limited at 6A, sso that would kill the LED... 100W Constant Current Boost Step-up Module Power check temps on that thing? id be curious as to how much light it actually produced and how warm it is 2-3" from the led edge and Lumens. at least 40 deg C
