I would be happy with a 4*7135. Really just want to be able to run it as bright as possible without getting too hot for around 10 minutes (for photography lighting).
it can be installed in S3 and C8,
but S2+ is not suitable
KY CSLNM1.FY ,it’s not pure yellow light .
Like the green light, it uses the design of coating phosphor powder on the blue chip. I can actually think of it as a warm yellow light with a color temperature of 1800K.
Thanks, just put in an order!
No way, what I need to replace is this in a custom build:
Which as far as I know, is the same part as an L2 smooth reflector (with ∅9mm hole).

S21A/B should be OK?

[quote=Simon Mao]
not suitable for S21A/B
it’s 17mm diameter
One problem in this chart - the U designation is for both the Boost HL and Boost HX
So I would change the text to: "Boost HL/HX"
With 20 to 17mm adapter?
And the same as L21A.
I ordered one a few weeks ago, should be here soon.
I was a bit too enthusiastic with filing :person_facepalming:
you can order a L6 reflector and add a note L21A reflector.
Well I am glad I have a spare S3 host lying around, but could you please note such unobvious limitations in the description of the items?
Additionally to what has been pinpointed by Tom E (the “U” 4040 footprint is for both Boost HL and HX), concerning the color or output type note that those with a letter in their suffix are phosphor converted emitters with blue pump (white TG, yellow FY and pure green F1) whereas those with just numbers in their suffix are native pumped “monochromatic” light sources (blue 14, true green 13 and red 23).
Which of the current LH351D from Simon/Convoy to take now - 4000k vs 5000k?
I’m going to try S2+ with new 5A driver after calming comments, that it’s not going to melt.
It’s just a matter of personal preference. 4000K is more on the warm side. 5000K is considered to be neutral white. But both render colors very well.
I wanted to go 4000k (which I already did for my T2, on the way to me), until I read some stories about 4000k being too green.
I find the couple of 5000k I have to be more green than the 4000, but ymmv.
If you can do it, I’d recommend the 5000k then slice the dome off
No slicing for me 
I don’t want to break it, immediatelly after getting.
But that’s the tinkerer’s way
