XM-L2 brighter due to higher forward voltage?

Ah, I was answering a question that you hadn’t asked :slight_smile:

Truthfully, I don’t have an XM-L2 handy at the moment, and I can’t think of anything off the top of my head.

Good example, thanks.

@bose: the strips of wires(?) over the XM-L block the light?

New and improved, extra fluffy phosphor?

BINGO!

Not the only thing but a major part of the increase, the single biggest.

Yay! What were they used for? Current spreaders?

Exactly.

:smiley: :smiley: :smiley:

So that’s what improved the tint! Shoulda known…fluffy=warmth

Weeding out correlation from causality is always a problem.

On the XM-L2, what is the function of the wire on the right of the dome that is not touching the phosphor layer?

Willing to bet it’s the ESD protection, I actually don’t know so this is just a guess.

So there is more than one way to take advantage of the increased efficiency. One is to use a boost buck driver and run the xml2 at 3A+. Another would be to run the xml2 at a lower current(2.6-2.7A) and realize the efficiency gain in run time keeping output more constant. Thus would allow continued use of 7135 based drivers without loss of time in regulation. Obvious stuff but might as well say it.

Perhaps there will come out some small regulated drivers which are suitable for xml2 and variable like the 7135…I hope so.

Entshuldigung sie bitte :slight_smile:
but I couldn’t find where this is variable

I think he meant versatile or flexible. Easy to use, fills almost any needs..

Sehr gut. . .:slight_smile:

Jawoll!

Yes, I hope so too.
Aber schnell…!

(We might get a really nice custom driver offered by lightmalls though)

For example you can add some 7135 or remove some so you can adjust the max current also you can program up your custom firmware…this is really versatile and cheap…
