Lumens factory E2 led bulbs and heads

[turbodog]

I have an old L4 that I am looking at upgrading. I can either (A) use an old e2 head with a 'bulb' replacement or (B) replace the entire head.

(A)
On this drop in:

Any idea why they say "no" to protected cells?


(B)
Also, this replacement head:

Is the led part of the head (potted/etc) or is this the led 'bulb' from my first link placed in a reflector head. I'm hoping this has better heatsinking than using option (A) with an old e2 head.

Protected cells are to long and can destroy the led board.

Is this from actual experience? My protected 16650 are the same length as 2x123 primaries.

No. Just from what I was told by them. I had the same question because the way they write it,it sounds like you will blow up if you use protective cells. So I got hold of them an asked and that was their response. They are to long and can/will damage the led board.
