I’m looking to remove the AC from there and get something that will provide same light but based on battery.
1. Any idea what to put in there ? I don’t need case or anything, just battery socket and let
2. What battery can I use there to provide me long operation time (its usually 5 hours a night on), I was thinking 18650 since I already have few.
You could do the traditional led, driver, battery by disassmbling an inexpensive flashlight and mounting the LED externally. Then use the flashlight body to hold the driver and battery. Alternately, this combo claims 250 lumens.
Or you could modify this sewing machine light. Since it’s input is 5V, you could use a cheap battery bank to power it.
Hard to tell without any details. Eg, how is it switched on/off? How would you switch it on/off if powered by batteries? Intend to leave it on overnight? What if the cells run down (ie, you’d need lvp)? Etc., etc., etc.
The sewing machine is actually nice solution, just can’t find how bright it is.
Well, Anything goes, physical switch, remote.
It usually works 2-5 hours a nights, depends when I remember to shut it down.
and as for cells, this is why I prefered 18650 that I have in hand and can charge.
There are those boards you stick into a powerbank or other usb socket which either just light up, period, or which you can control (dim up/down, turn on/off, etc.).
This
gives you ww and cw in one.
Just get a usb adapter, powerbank, whatever, and go crazy.
Mount the doodads at the back so you just use a finger to touch the control-pad.
