These LEDs are warm white, very bright, and can dissipate 1 watt each. We don’t have lumen specs but they are painfully bright to look at when powered from about 1 watt (300 mA). Useful for a very wide range of illumination needs. We order the warm-white variety, because they seem generally more useful than the icy cold-white versions that have a slightly higher light output.
It’s probably a good idea to tie these to some copper or a heatsink when used at full power.
2.6V @ 20 mA
2.9V @ 100 mA
3.1V @ 300 mA
As mentioned in the datasheet below:
The anode side of the device is denoted by a hole in the lead frame. Electrical insulation between the case and the board. is required—slug of device is not electrically neutral. Do not electrically connect either the anode or cathode to the slug.
