First time trying this glue. I wouldn’t call it a super glue. Sets in 30 minutes cures in 24 hours. Don’t stick your fingers together like super glue does.
A 1/16th inch disk would probably been enough. Was thinking the hole could be filled with epoxy or black JB weld. I still might. I have had better luck completely covering neo magnets in the past. They tend to chip off on the edges. They are brittle.
K&J Magnets is where I found these. I will probably order some more. I remember a coated version.
I don’t feel I need to glue the clip. It has not moved at all in the few days I have carried it.
This is still a work in progress. I also would like a way to attach a small 3” loop lanyard. It might work on the clip itself. Will update.
I love magnetic tailcaps. Ideally, I fit a small magnet within the tailspring, but some lights won’t allow that.
For securing magnets to the outside of tailcaps, I’ve had good luck with Loctite 5-minute Clear Epoxy. I scratch up the nickel coating of the magnet and the anodizing of the tailcap before installing.
I suggest N52 grade magnets, which are stronger than N42 grade.
My Zebralight SC5w weighs 90 grams (3.2 oz) with an AA Eneloop installed.
Amazingly, a 1/32” thick x 3/4” diameter N52 magnet holds the SC5w to even a painted vertical steel surface. My H51w has one too.
The D4 with a cell weighs about 120 grams, so I’d go with at least a 1/16” thick N52 just to be safe.
I’d like a floodier version with XPL; the Nichia doesn’t have enough output and efficiency. Considering the result with the XPL-HD in the D4S, I’d like it in the D4 as well. Should maintain the lumens and drastically spread the beam.
I ordered mine with frosted optics,then got the narrow to swap. I noticed big difference. Almost like 2 different lights. They are both bright, lemons very close.
As others have suggested before, It would be so nice if Hank invested in developing a current regulated driver with the D4 user interface. Instead of making these 219C and SST-20 D4’s just hot and inefficient, they could be run in a much more efficient regime, with not that much lower output.
With more and more emitters with extreme low voltages, such regulated driver (perhaps even buck- ) would be an asset for the Emisar brand flashlights.
I wonder if it was feasable to order the D4 or D4S with a 2x2 array of SST20 5.000K with 6500K or 3000K with 4000K. I wouldn't want to mix 65CRI and 95CRI, though.
All builders could heed the voice of reason and sanity in this ‘sizzle sells’ market.
It is precisely why I use a MecArmy PT16/18 instead of my D4 lights.
