Mod Advice For a Cheapo Flashlight (switch issue)

I think I figured it now, I can see my pictures on my computer AND my phone. Please let me know if it’s still an issue.

i’d change the emitter, if nothing else to get the tint i might want

is the PCB sitting in a plastic pill? i wouldnt do a driver swap though, unless you get that worked out.

No images here. It comes up when you click on the picture link that you have to sign into your Google account.

i saw the pics, made my post… now they are gone…

if that timing helps…

Thanks for letting me know sedstar. I’ve reposted the pictures again so hopefully they appear now. Please be patient with me.

I see the pics for the first time!

No pics and no thumbnails. :frowning:

no images, no thumbs

I cant see them either…. you need to upload to an image host, copy the sharable link URL and post those here.

I use photobucket, but there are others.

The ?’s are still small but the boxes they were in are full size so that’s an improvement. :wink: how are you posting the images?

I question how i SAW THEM FINE, then they disappeared…

Is the hoster down?

They are hosted on some sort of Google site / service. I have seen people having problems with posting some Google hosted images on forums before. I forget the solution, but do believe there is one.

the solution is…

photobucket

Hi everyone, sorry for the technical difficulties! I tried so hard to make Google Photos work, but eventually gave up.

The first time I tried to submit a picture to BLF I created a Flickr account, but I didn’t use it since it seemed Google Photos was working. What’s strange is that the pictures looked fine when I viewed the postings, but apparently that was due to me being logged into Google.

I’m glad that I finally got this figured out and thank you for your patience.

If you put a new led and star it’s going to sit much lower in the light.
Right now the led is very tall and provides the dimension to hold the reflector against the lens.
IMO I don’t think this light is worth modding.

Not worth much, plastic pill, so no thermal path. You might be able to swap an original XR-E in there and get some better output, if you have spares laying around in your kit.

I don’t think dedoming would be worth trying in that light, but I have seen some of those cheap emitters where the dome was just a clear protective plastic cap…

In fact, you could probably find a better fried egg style emitter than what’s in there, but I don’t think it would be worth it. I give lights like that to little kids as toys since they won’t start fires or blind anyone with them.

what about just making a metal pill to replace the plastic one? looks like maybe a press fit on the plastic pill? if its a press fit, its do-able…

I’m just so excited that everyone can see the pictures!

My main goal for a modification would be to change the tint to be more neutral, not for any more lumens. I’d be fine with less lumens as long as the tint was improved.

Is there a LED that would work with the current driver?

Would this one work: Nichia 219C D280 on 16mm Noctigon - 80+ CRI 5000K

Or would it not be compatible?

thats one of those ~1 watt emitters, so it probably sees ~350mah

You could try replacing it with a better emitter on a 16mm board. It will have no thermal path and no mass beyond the MCPCB though, and its anybodys guess how well the die sits relative to the focal point of that reflector. I don’t think todays cree emitters generate much heat at that current… let others correct me though. A more experienced member could probably tell you exactly what that driver does just by looking at it.
