really a question
will this kill algae. I'm trying to put a few UV-C lamps(the type that kills algae) in my fish tanks pump.

risistance
perhaps the first poster had a problem because they didn't use the right resistance. use V=IR use for V voltage to be dropped. so 5-3.7+1.3 so plug 1.3 in for V 1.3=.02R R=65 ohms that would help make your led a bit brighter.

Awesome
I have an old car (1987 Plymouth) and the dashboard lights are all incandescent and rather dim (or burnt out). Since I drive home at night fairly often, not being able to clearly see my speed has been a problem (haven't been pulled over yet, thankfully :). I had modified the bulb holders with a resistor and an LED in each, but that didn't prove to work so well. This time I surrounded the perimeter of the gauges with the UV LEDs and went over the white letters in orange highlighter. The effect is simply amazing. I am using 5 of them in series-parallel straight off of my car's 13.8v. When they're working you'll know it. They produce a fairly bright purple when lit, but if you stare into it it'll feel like its much more powerful, leaving behind a spot in your eye.
Great LED!

LED Longevity
The lifespan of these (barring flaws in manufacture) should be 60,000 to 100,000 hours depending on how hard they're pushed with voltage, on/off cycles, and temperature.

UV disinfection
To the person who asked about using these to stop algae: The UV must be strong enough or this won't work. You can try but I wouldn't bank on it. I'd get a real disinfecting UV lamp or find out how much output they have and get a similarly powerful black light.
