3 Minute 30 Cent Mods

nottawhackjob · 2018-07-22T21:57:51.000Z

If you’re gonna describe something getting modded by filing, altering dimensions, affixing it to some other part, etc., then provide pictures, sketches, links, whatever, or it can be confusing cuz what I THINK you said may not be what you MEANT and what you meant may not be exactly what ya DID.

A picture sez a thousand words and a thousand words may still not really get the picture.

IOW what the hell did ya do and most importantly HOW did ya do it? I mean if we’re gonna try and make things truly stupid simple.

:laughing: :sunglasses:

• 20mm TIR lens of your choice dropped into an S2+ in place of the reflector. Beautiful blending of the beam, especially the 4C (beautiful warm-sunlight color) and no fried-egginess of the beam at all anymore.

• Fasttech deep-carry clip (advertised for the S2/S2+) which fits the Nitefox UT20 and similar lights as if it were specially made for them, even down to the color/matte of the finish.

Do you have a link to the TIR you use in the S2+?

Too many. I went to Amazon and just goggled “20mm collimating lens” (yeah, go figure) and got a bunch from LEDsupply.

Got some coming in from AX, some generic supplier for a 5pak of 10pak or whatever,

Best bet as to being choosy is from LEDsupply. I’ll go find the link…

That was easy…

If you want a 20pak or so, Amazon’s the place. Probably won’t have to wait 3mos to get it.

Ugh, was phrased horribly.

I got a bunch from LEDsupply.

Before that, I went to Amazon and found some TIRs, but “TIR” was nowhere to be found in the description, only “collimating lens” in various combinations’n’permutations. Narrow it down with “20mm” if you want to.

LEDsupply lets you order singly, etc., but Amazon usually has bulk paks of 20 or more.

Thanks , will give it a try.

Slayer1 · 2018-07-23T02:19:11.000Z

I got mine from here : leddna.com

Lightbringer · 2018-07-23T02:43:39.000Z

Oh, LEDsupply also has 26mm TIRs in case you want to a D26/P60/P90, but you’ll need a spacer to make up for the TIR height vs reflector height.

Still not reflowing my own led’s, I always buy them on a pcb. Especially the alu ones tend to be a bit warped. Every new pcb+led that goes into one of my lights, gets a flattening trip on a lapping stone. But a sheet of fine sandpaper on a glass plate also will do the trick. It makes better contact (IMHO) and saves on thermal grease. You only need a hint instead of a blob.

Not sure of the correct size for S2+. Does the emitter type matter? I found these 45degree ones on Amazon. I am guessing 45 degree will give smooth beam?

Also, at the Led site , I see various models that have the same specs. For instance , I see different numbers for 20mm wide angle ripple but no way of knowing what the difference is between them . Are holders needed for S2+?

Lightbringer · 2018-07-23T16:47:32.000Z

20mm is the “right” size, but they might be listed as 20.1mm or some rot like that. They fit.

The inside of the front bezel keeps the TIR more or less flat, and as long as the LED is centered in the hole, all should be okay. XM vs XP (5050 vs 3535) shouldn’t make much difference, especially with a wider-angle lens.

Ideally, TIRs should have the “shoe” that acts as a centering ring and spacer, lifting the lens just a smidge off the pcb, but it’s not critical. I wedged one in there, had a hard time doing so, but it worked. Also worked well without it, either.

Just get an assortment, play around with it, and you’ll likely find one that suits you.

60° is a nice flooder, especially for a headlamp, but also in a S2/S2+ that’s mainly to be used close-in and you’d want it to be nice and floody.

Will a XHP50.2 fit under one of these? With boost drivers coming (eventually) this may be good way to clean up a 50.2 beam in a S2+ host

eas · 2018-07-23T23:18:34.000Z

XHP50.2 is basically the same form factor as XM-L/2, 5mmx5mm.

pennzy · 2018-07-24T00:13:09.000Z

All this talk of lens got me to thinking about DC Fix . I have been meaning to use it on a C8 to smooth out the beam. Finally got around to it . Looks much better on the wall . Won’t be able to test it outside tonight because we are in a frickin monsoon this week in NEPA.

That is only the footprint though. Its a decent amount taller

Nice tip Henk4U2! Where were you many, many mods ago? For a recent mod I was filing down the edge of a copper 3 LED MCPCB after I made it smaller and then ran the bottom of it over the file and was surprised the middle around the hole actually filed down more than the rest.

NeutralFan · 2018-07-24T01:41:42.000Z

A no cost simple mod you can do if you have a beam with artifacts is to take your glass lens and sand down 1 of the sides with medium grit sandpaper. Not sure if it will work with an AR lens or a big lens. I did it with a Convoy S2+. Just press the lens down hard on the sandpaper and move it back and forth in 1 direction, rotate the lens, sand some more, and continue until the etching (i.e. scratches) is consistent across the lens.

If it doesn’t work the first time, you can start over again on the same side. It took me 4-5 attempts until it turned out to my satisfaction. And I was shocked as to how well it smoothed out the beam. The LED had a crack in the dome which caused a very annoying artifact. This mod smoothed everything out perfectly.

And as a bonus, the lens is still glass so it remains durable.
