Planning to wire 3 cree Q5 in serial configuration. Will this driver do? The current will be limited to 900mA and the voltage applied would be 3x the LED Vf right? It is a current limiter... correct?
Also it this okayish to wire in serial 3 XM-L's?
Bumpity bump!
No1 ever powered cree leds from an mains AC outlet?
Im not much of an electrician but so far i gathered that i can be sloppy regarding higher voltages to emitters as long as current is limited... Still it's a whole world of things to consider about decently powering led emitters. Going to industrial grade leds seems like a more sound choice but i would prefer cree's flashlight emitters foo the task as long those will be powered for up to 3h at once and not for constant light sources. Can't beat power/lumen ratio of the latest flashlight leds.
The first one (900mA, 9-12V) should be OK for 3 cree Q5 in serial configuration.
The second one isn't well specified; does it do constant current or constant voltage? It only says 12V 2.5A ... 3 XM-Ls take 10V, not 12.
On the other hand it says LED CONVERTER, which suggests constant current, and it won't be able to deliver more than 2.5A anyway, so I guess it's ok. I'd measure the current and test if it runs stable though.
