Looks like I will just go for that then, the 2.9mm thickness might work fine without a spacer anyway.
Is there anyone who has AR coated glass where we could get lenses cut from?
Would not be too difficult if the material is available.
Just jumped on there, looks like the stock a nice thick 3mm acrylic AR coated lens, but nothing much in the offerings with glass available.
Might be worth a shot anyway. Glass is more scratch resistant, but this is still going to be better than a factory maglite lens.
I think that since the...
Not sure about LED yet, but was looking at a cree XHP70, but not sure what other high CRI options there are out there.
The highest CRI version is this here I believe https://www.arrow.com/en/products/xhp70a-01-0000-0d0uj445g/cree
I plan on using a 3C light with 2x26650 inside, so should give be...
I just bought this optic from digikey.
It's made by khatod and the model no is PL50SIL.
It fits perfectly in the maglite and drops in flush rather than sitting on top like the reflector, but it can be addressed by making a spacer or using a thicker glass.
Finding TIR optics the right size is...
All I know is less is more when it comes to this.
Not sure if the same applies to the epoxy, but I would assume so.
Most builders seem to epoxy their LEDs to the pill rather than use thermal grease and screws.
Another mistake people do is fill the pill up with Fujik silicone compound.
In many...
I can probably do fine with two 26650 in a 3xC cell light, but with a 2xC light, I would only fit in one 26650, so cant really make full use of the space inside the light.
Yes I think you do have to bore them out on some lights. I think a brake cylinder honing tool would work well for this.
Im...
Still cant see anything there, seems most optics listed there are not much more than 30mm diameter.
I need something ~2 inches or 51~53MM diameter
The closest thing i can find is this.
Never heard of silicone optics before...
I was wanting to mod a C size flashlight to LED and use lithium batteries.
25500 seem to be rather hard to find with no big name brands producing them.
This is the best I can find here, but have no idea on the quality...
OK, that makes sense.
I guess what I had in mind was that if I found a (lower CRI) light at a lower output at a comparable brightness mode, I could in theory extend the running time. e.g run the cool white at 3 lumens instead of 5, I was assuming that would give me a bit longer runtime...
OK, the way I took what you said when "most LEDs that are efficient in brightness, are low cri" that it meant that such LED's would give you more battery life for given amount of lumens per watt.
Might look into the manker, I think what put it off for me was it was a right angled light and cant...
Thanks for reviewing the maratac anyway, I know to stay clear of it.
I will grab a thrunite anyway and try it out for its price. For my application, battery life is more important than CRI anyway, but obviously its beneficial. I certainly love the Nichia 219C
No doubt we will see huge...
