I am quite new to led lightning technology and I am currently upgrading a diving lamp. I currently have three 3V Cree XHP50.2 White 6500K LEDs which I will mount on my old light head. Only problem now is that I can’t find a proper driver for the setup. I am using 3s Li-ion battery. Driver will be mounted in a syringe with diameter of 25mm. Since the lamp will be used underwater, heat should not be a problem. Could anyone give me some advice what driver should I buy?
How do you connect the emitters 3s or 3p ?
Probably 3s but if anyone has better ideas 3p isn’t a problem
22mm FET from MTN Electronics is probably easiest solution. Not very efficient, but many options available for your liking.
Do you know any sites that offer those kind of drivers in Europe? Shipping costs for The US will be quite expensive compared to the price of the driver itself. And how high can the current be with that driver?
Do you happen to be Finnish? If so I might help.
That’s correct
