David
The tint goes warmer yes, it’s not an exact science, ie. I could de dome identical emitters and both might have slightly different tints, but both will be warmer than the original tint, the tint can go blue if the phosphor layer is removed whilst de-doming.
I’ve noticed green tints when the emitter is driven at lower Amps when the emitter is driven hard the tint restores to the right tint.

In simple terms I go for after de dome are:

Cool white = neutral white
Neutral white = warm white
Warm white = extra warm white
Etc etc
Basically drops a “category”

I’d say at a guess the de dome loses 1000-1500K maybe
So 6500-7000K becomes 5500-6000K

I’ve sent you a de domed 5000-5500K emitter T6-3B ( as I said in an earlier post I don’t go off this it use colour temperature {K})
So in theory the tint will drop from neutral to warm as a rough guide, (5000-5500K to 4000-4500K) if you want a neutral white tint after de dome then you go for a cool white emitter, make sense?

I don’t like going into technical words and I like to keep it simple so I hope that’s helped?

It came in the mail today! Well packed, de-domed, and everything as promised. I briefly put power to it to make sure it was not DOA. It fired up, and to my untrained eye, it looked a little yellow (warm). Thanks for the explanation of tint shift. I had read that it would shift to a warmer light, but didn’t know how much.

When I get nailed down to what exactly I’m gonna do with it (thinking of modding my 2D Mag-Lite) I will do a build thread for all the world to see (Yes, that will be another first for me – Woo-hoo!) But for now, I’m happy. I had an XM-L2 already that I’d bought and wondered what de-doming would do to the light output, but was unwilling to try it myself. This way, I don’t have to, and I can compare them side-by-side as well. Thanks again, James. And thanks to all my loyal fans who made this possible. Oh wait, I don’t have any of those. Silly

I’m Glad you like it David Smile yes non of the LEDs should be DOA on arrival because I thoroughly test each individual led.
You’ll probably see with yours that it’s quite a warm tint, light output wise there will be less lumens after de dome but more lux so to the eye it will look brighter and have a more concentrated beam and further throw, the warm colour will look good in a mag-lite, but if you want a cooler tint you know where to come Wink

To people who don’t know what de-doming does, I describe it as like shining a light through a glass/vase, the light on the other side will come out ‘distorted’ if you take away the glass/vase the light will come out cleaner and more concentrated, obviously the glass/vase would be the dome of the led, I don’t know if that helped anyone but that’s how I see it!

But let me know how your build goes, and post some pics on this thread, I’d love to see how it goes and what type of things my leds end up in!

I ‘knew’ it wouldn’t be DOA, but I wanted to check it just to confirm for anyone who might be listening in. Discerning buyers always want to know these things and would think it strange if I praised the merits of the LED without having tested it at all. Plus, I just wanted to see it shine. It will be a little while before this goes into anything, because I have other projects I’m working on. But, I will keep you posted. And I may very well get some cooler tinted LED’s from you in the future. I prefer the range from NW to CW for most things. But, there ain’t nuthin’ wrong with a little warmer light from time to time. Wink

Sorry yes was just stating that I’m not a big manufacturer and that I check each and every one before I send, unlike some big companies Smile I do appreciate you telling others about my work! Positive feedback is always good, Yes keep me posted as I said I’d love to see pictures of the finished build and let me know if you need any more emitters!

Guys last day for introductory offer de dome!

Also, would people be interested in me offering de-domed emitters on the standard aluminium boards? Obviously at a cheaper price?

Edit: Aluminium XML2 16/20mm = £3.00 Aluminium XPG2 16/20mm= £2.00

£6.00 all in for XML2 de dome aluminium vs £8.00 noctigon £5.00 all in for XPG2 de dome aluminium vs £7.00 noctigon

-Guys as you know I’m going away on Friday, I want to do a giveaway before I go, something different from last time though, last time I just gave it away to the first person who commented, I want to make it a bit more fun this time, any ideas appreciated maybe a little contest? It will only be a short one finishing Thursday morning UK time. I don’t know what it will be yet, couple of emitters maybe. -

Now offering P60 lead heat sinks as in the picture below, made of lead, work great for heat management, can be sanded down for the beefier drivers.

£2 each

I'm curious as to why lead?  It has a very low thermal conductivity compared to other metals.

My lights here and here

There’s been no ideas yet for a giveaway, last time I just gave an emitter away to the first person who claimed it, I want to do something different this time.

It’s quick cheap and easy to cast and it is only being used in p60 dropins there for most likely a ‘small’ light anyway that will only need a bit of extra heat sinking, they are obviously not good for an mtg2 dropin or similar.

It’s basically just a cheap option for someone who needs that little bit extra, without having the expense of getting a copper one casted.

Well might give it to the last of a certain word before a certain time ?

Or let someone do a review of the same type domed and de-domed led ? (for example, i can do macro shots of the led, and take gray card balanced pics of the color change between the domed and de-domed led, with neutral daylight as balance )

Okay, I was gonna stay outta this, as I still owe James a build thread from the last GAW. But, I just thought I’d check in to suggest a GAW idea. How about you get people to tell you their cleverest use of a LED emitter (whether in a flashlight or not) and you either choose the one you like most, or put it up to a vote or something.

I’m quite liking the idea of a review, maybe a video review from unboxing then on the emitters, or if not video then a photo review? As mentioned by Lanwolf the macro and grey balance would be a good idea? Any thoughts?

I think a thorough review would be a great idea, but how to use that for a GAW? Choosing randomly wouldn’t insure a proper review would take place. You could do as others have done recently – take a vote.

Review it is! (In depth Video or photo review) How do the votes work? I’ve not seen that?

I’d love to do a photo review. I’m a long time photographer, mostly nature. (That also incuedes macro photography (most used equiment at the moment are canon 6d, 24-70, and 50mm)

Have you done any reviews/photographs on flashlights/components before?

Haven’t done flashlight reviews, nor photographs on flashlights.

You can although see my writing style and find snapshots i made with my iphone in Here (yes there are some badly focussed pics too, but that didn’t matter, it showed the essence) and over here at cpf , and some more pics of baked flashlight later on. All taken with iPhone.

Most pictures i post on forums, are made with my iphone, for a (photo)review of course i would use my canon in the studio (or take it to my workbench)
