really bright (around 10 watt) LED

This is a quick demonstration video for a LED module that can put out 10 watts, or more, the actual limit is ~13 watts if you can keep it below 100C. Rated at 270 lumens, 80,000 mili-candela. There is one above this that is 380 lm, 122,000 mCD (around 14W) but I haven't built the driver for that one yet.

Here is a link to the parts on Digikey.

Note that with most high-wattage LEDs like this, a proper "LED driver" (constant current driver circuit) is required to run them. If you don't know what this is or how to build it, Digi-key does have predesigned modules that do a good job for around $10.00. For example: the 700mA LED driver below:

Look at the datasheet for more details of how to hook these up. A driver like the one given above is a BUCK driver so you must be roughly 2 volts higher than the LEDs rated voltage (which is actually just an estimate).

Ok, it seems to be fading out... Is it or is it just the camera adjusting to the light. And what do you mean you had to build drivers for it? Is this not a 12 volt led? Thanks

Just the camera's auto-exposure adjustment, yes.

LEDs this powerful generally require a constant-current driver circuit. The customary voltage source -> resistor -> LED -> ground type circuit will not do a good job, the brightness will vary too much and burnout is also a risk.

[SimonBearSr02]

ok good to know. I wanted to wire these onto my motorcycle but you say that it NEEDS the constant-current driver circuit? would a power conditioner work to keep the voltage from spiking?

[AccessAccess]

I don't think so. I added a digikey link to a driver module. You've got to run it through one of those. The problem is that as the LED changes temperature, the properties change. Now it's also been a year and a half since I made this video and today the LEDs out there today are even better.

may i ask if you have some documentation for this bright diod light, and were can i finde it?

[AccessAccess]

OK, I added a link to it in the video description.

What a waste of 25 seconds!

Switch It ON!! i cant see it clearly :x
