To me, not worth spending that kind of money.
True. I bought as a host for about $30 and I still have no idea what to do with it.
How did you get a host? Was it only missing LED's and the driver/ Or other parts missing as well?
Ohh - see it now at the Ali store, but it's listed for $50 now :FACEPALM:
4x 2mm WF and a FET driver would make a pretty potent combo. Would draw more than 20A from a good cell.
That combo would be pretty similar to a SBT90.2. Similar light emitting area and current density. Before this LED was available a multi emitter light was the only way to get high output and high intensity. Now we can get that sort of performance from a single reflector.
