I know this is a dumb question. But I have been a direct drive fan. The objections: 1. your batteries must be brand new (issue fading, as I have heavily invested in smart charger and found 3 brands of trusted batteries.) 2. I don't like sudden off (probably no longer an issue, more lights just dropping down.) 3. Low efficiency. (Issue fading as better circuitry, less pwm, more current controll.) 3. I have had 3 or more controllers die within months. (Might not be an issue with quality controllers, just an unknown when buying a new light.)
Well my u2 controller went poof after 2 days of ownership. I am not holding my breath on a replacement. I think it is time I educated myself on controllers to choose a quality one. Specs for ideal one: 1. quality 2. no pwm 3. 2.9v to 7.2 volt input (i dream here.) 4. At least 4 AA worthy. (I got one 18650, but still way too hard/expensive to get parts (holders, extra chargers, multi bay charger with at least 4 bays, extra batteries.) . 5. Draw from 4 AA cells should average 300 milliamp and 600 milliamps.
Now the dumb question: what controller w/ all harness, on/off, pot can I buy complete for a 4.8 volt AA supply?
My thinking is http://www.ledsupply.com/03023-d-e-500p.php or 700. But the specs say 5 volt minimum, I suspect this number is not accurate, as I see others on googling using 4 AA with these, I think. Then, what are you supposed to use for the built in pot; what is good setup?
I would contact ledsupply, but think real users better than sales staff.
