High Power LED Flasher  August 3, 2008
Power LEDs are becoming more popular these days. The DC input power to these devices ranges from 1 watt to 5 watts. Normal LEDs only receive about 0.05 watts. At this higher power, these devices can emit a lot of light. You can buy them in just about any color in the rainbow but white seems to be the most popular. One application for these devices is a flashing light. If the flash duration and flash rate is kept low, the average current can be low enough that even a small battery can last quite a while.
