NEW PRODUCT – 1 Watt Cool White LED – Heatsink Mounted

Window-6

NEW PRODUCT – 1 Watt Cool White LED – Heatsink Mounted. Make a 1 Watt flashlight or a headlamp with this ultra-bright LED. The LED is very bright, with 90 Lumens in a 140 degree lambertian pattern. Compared to most LEDs, you would say this is 30,000 millicandela. Either way, its incredibly bright! The output is a ‘cool’ 6000K pure white, not a ‘warm’ incandescent-looking white.

Window-1-5

The LED is mounted onto an aluminum PCB for heatsinking, and it also makes it easy to solder in. Simply connect to the big + and – pads on the PCB (there are two of each).

The best way to drive these LEDs is constant current, @ 350 mA, but you can get away with under-driving for compactness. At about 3V, the LED draws ~200 mA, so connect two Alkaline batteries up directly with no resistor for a basic bright lamp. You can also try driving it directly with a 3.3V power supply, that will probably work OK as well (although its not ideal) – that’s what we did when we made a vintage LED bike light using a 1W white LED.

  1. Doesn’t the internal resistance of the batteries play a large role in the current without an additional resistor in the circuit? This could vary significantly between alkaline batteries, and especially with other battery chemistries or a power supply, right?

  2. @sparr and @K probably good questions for the forums so we can help the most people out at once (and also keep the discussion going, blog comments close out a week after the posts to limit spam)…

  3. I see from the datasheet that in addition to the 6000K version you’re carrying, they also make a 3200K version… any chance you would consider carrying that as well? 3200K would be handy if you needed to match incandescent lighting.

    I’m thinking that if I made an array of the 3200K and 6000K LEDs plus some way to control them (maybe using that neato lux sensor you have now to get constant total output) then I could dial up light that would match any color balance from incandescent to "open shade," which would be pretty handy for photo and video applications.
