hi cpfers
i picked up this 6x LED work light from a local shop.
it is rated for 1.3amp at 12v, and i have measure this to be accurate with a meter.
it appears to be preforming as specified on the label.
BUT, after 30mins hooked up to a 12v lead battery the unit is hot to touch. enough to hold it for 10secs without pain. this i am ok with.
but after 1 hour, it is too hot to touch, this i am NOT ok with this. light output appears normal.
unfortunately the unit is glued and can not be disassembled without great effort.
but looking through the lens i can see that there is a driver on the board where the emitters are seated. i am not surprised since the unit says 10-30volts which suggests regulation.
my intention for this light was to be on a garage hooked into a 12v solar system.
but the heat issue gives me concern that it will not last long, or worse become a hazard.
my questions;
1. is this unit too hot or is this normal for this type of worklight? can it handle this heat for 6 hours daily?
2. because i can see a driver inside already, i assume this means i can not PWM regulate its supply without sending the built-in driver nuts
3. am i wiring this correctly by hooking to straight to 12v (considering its regulated internally)?
pre-thanks!
