After reading Old Lumen’s shower head build thread I took a trip to the closest TSC and picked up the same $9.99 100 led “Jobsmart” light. I bored the head to 1.505” and re-threaded to 20 TPI to fit the mag tube. I also cut out the first couple threads so it will screw all the way down to cover the o-ring.
3D Mag
The jobsmart head has 2 cuts on narrowest part that make wall thickness extremely thin. I honestly wasn’t sure if the threads were going to break out.
Business end is a single XML driven at 2800ma from a 8x7135 board with the blinky and flashy mode disabled. Batteries are 3 8000mah nimh from Tenergy.The reflector came from an old Hitachi work light I had and seems to work well.
I had to adjust up the heat sink pretty high out of the tube to get the focus right. with the stock mag head it sit just slightly above the tube.
Yep, it helps a lot to have access to the necessary tools. We are gonna need beam shots. I'm interested in how that incandescent reflector will perform with the XM-L in it.
You got a deal on that Jobsmart. I paid $19.99 for the one I got.
You are right. I paid $19.99 for it. I bought some christmas gifts for my dad and a Dominator scraper for myself. I thought it was only $10 so I never really looked.
Up close <8 feet the beam has an ugly hole in the middle. Probably cause the emitter sits about .375 up in the reflector. The hotspot looks good at any sort of distance and hits the tree tops a few houses away. In the night sky it shoots a visible beam strait up and a spill of probably 90 degrees or so.
I’ll try and take beam shots but I can’t guarantee they won’t be fuzzy.
Well the black 3D had to go back to the friend I modded it for, so now the shower head has no home. Rewind a year ago I made heatsink out of brass and soldered the mag bulb collar to it to make a screw on drop in. So I aa’d on an XML-t6 a few months ago (it sat idle for that long) and put in a 3d mag. I realized right away that the height was to tall to work with any reflector I had.
Fast forward and hour ago I was thinking about the shower head with the work light reflector and how the led needs to get up real far for it to right. Well the 2 seemed like a perfect fit. Add those to a spare 1D host with 4 “Duraloops” in a holder and I’ m making light again. With all that said it will most likely come apart agian until it finds a final home or til the 75mm sst-90 reflector get here.
