Well, I’ve been around here a while, but I still consider myself to be a noob! Maybe not any more, though. After all, I’ve been giving my opinion on various threads for quite a while now as if I know something (HA!). I also completed my first BLF / Old Lumens Scratch Made Light Contest light this past go-round. I’ve secretly been doing simple mods along the way, but never posted a thread on one. ImA4Wheelr’s (currently running) Giveaway, in which he requires the entrants to post a link to one of their mod threads, finally convinced me that I needed to do this thing! So, here we go…
I modded a tiny zoomie light that I picked up at Lowe’s a while back. I had bought the light just for the purpose of modding. In fact, I even designed a driver board to go in it. But, when I looked at it again, I realized my design had a flaw that made it unsuitable for this light. So, I decided to proceed without a driver. I took pictures along the way, so I’ll let them do most of the talking from here on.
Here’s the light. It’s a zoomie. It has a clicky switch. And it came with four button cells in series directly powering the cheap 1/2-watt LED in the head.
Pieces-parts all over the place! You can see it’s actually not too shabby for a cheapie little light. It has a screw-in pill, orings around the head, the pill, and the tailcap, and a decent-looking clicky switch.
Here’s the LED. The PCB has vias around the rim where it grounds to the shell. The spring is soldered directly to the other leg of the LED.
Here’s the PCB I’m going to use for the LED. The original PCB was mounted to the underside of the pill, so I’ll use it as a contact board. I just had to remove the LED from this board, file it down to size, and solder a Nichia 119B where the cheapie LED was.
I drilled through the PCB (yeah, after the LED was soldered on), so I’d have a way to get the wires to the top. I soldered the wires to the original PCB where the LED had been.
Then, I put the two PCB’s in the pill, pulled the wires through the holes and soldered them down. Finally, I put it all back together. I tested it with the four button cells, then took them out and stuck a 10180 inside.
Beamshots are up next. First with the button cells, then with the 10180. I forgot to take a picture of the beam before the modification for comparison. Sorry about that. Oh yeah, sorry about the junk in the pictures as well. These pics were taken in my basement.
Well, I hope you liked it. I had fun. I did some things I hadn’t done before, and it worked anyway, so yeah, good stuff! I may one day fix my driver design and use that to do one of these again, with a brighter LED - and modes! I’m kinda bummed I didn’t get to use a driver in this one. I think for it’s size, it could really impress even normal, non-flashaholic people if it had a little more output and some fancy mode switching. But, I’m still happy with how it turned out. Thanks for watching!
