TIPS FOR PLAYING WITH HIGH OUTPUT LED’s
1) It is always necessary to provide some sort of heatsink when using these LED’s. I use a piece of aluminum or copper slug to provide a thermal mass and dissipate the heat. There are several good heatsinks available on the retail market as well. When building flashlights, the flashlight body, if thermally conductive, makes a great heatsink. Maglight bodies are excellent fort his.
2) It is best to thermally bond the LED to the heatsink. I use a two part compound- Locktite 383. There are other materials that are available that work very well.
3) The heatsink must be electrically isolated from the power leads, this is especially important when mounting more than one LED to the same heatsink.
4) These type of LED's require a driver circuit, you can't just hook them up to batteries
