I have a drop in replacement bulb thats pulling 4.6 amps and measures 3.5 Volts on 3 D NiMh 9000Mah batteries? Its the replacement from qualityitemsonline.com. Whats the max a luxeon 3 watter can take? And any more info would be great!!!
Under nominal conditions, Lumileds rates the Luxeon III at a maximum of 1000mA (1 amp). If you can keep the die cool enough, you can push more current through the emitter, but at the price of lower efficiency and more heat.
I hear that the gold bond wires inside the package are prone to failure when more than 3A flow through them.
I was measuring it wrong I tested it the right way and got .5 amps using 10amp max on my multimeter and it showed 144 on the max current function of 400Ma. I put one probe on the positive lead to the LED and the other on the battery. So any suggestions which function is correct?
OK I have it all figured out now sorry bout all the mix up I was shorting it and getting 4 amps it's really 620Ma at 3.36V and 80C is the temp after like 15mins. Now that thats all figured out what is a good max temp for a 3 watter and max amp draw for my upcoming project I want to use 4 3watters on a custom sink I have. So what is the best star for this since I've heard about different BIN's producing different forward voltage . I'm looking to use LXHL-LW3C is there abetter white 3 watter?
