Description
This incredibly bright LED is rated to 90 Lumens (Approx. 30000 millicandela) – perfect for a DIY flashlight. The output is a cool / pure white in the 6000k range.
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, however this is not an ideal setup.
The LED will get fairly warm, a heatsink PCB is highly recommended. These are a perfect fit on our Aluminum Mounting PCB / Heatsink .
Please Note: These LEDs are incredibly bright and should not be looked at directly when switched on.
