High Wattage LED Polarity

After recieving a shipment of 100w & 50w LEDs we realized that without any paperwork or data sheet we needed to identify the polarity of the LED terminals. There is a plus and minus sign but its not clearly associated with one terminal or another. Although all three are the same brand LED (Lohas-LED) the plus & minus are in different locations on the 50w LED compared to the 100w LEDs. With a digital multi meter we were able to ID the correct terminals.

 

High Power LEDs: 50w Red, 100w Cool White, 100w Warm White

 

High Wattage LEDs will be used to make flashlights and various other lights. Have more due to arrive by mail. If all goes well with these will order some 500w LEDs for a 1,500 watt super torch. No paperwork came with them so I still have to find out the current ratings and polarity was not clearly marked. Look for future videos.

 

100 Watt Cool White LED & 50 Watt Red LED

A look at super bright high wattage LEDs, 100 Watt Cool White & 50 Watt Red. Mounted to a passive aluminum heat sink and powered by a bench power supply.

100 Watt LED Glows Without Power

High wattage LEDs glowing without any power applied. Each of three LEDs behaving differently, 100W Cool White LED, 100W Warm White LED & 50W Red LED. Free energy or just a cool Fluorescence effect? Note how the center row of LEDs in the 100W Cool White LED Glow differently than other 90 LEDs on the same chip!
