I would but now that i have looked up what the FW3A is, that is too nice to tear apart. Eventually it may become part of my daily rotation.

Then just get the FW3A to use in stock form and experience the SST20 that way. Smile

User BlueSwordM ran a group buy, but has reported it is now all done:

Kaidomain.com and intl-outdoor.com sell bare SST20’s, although the FB4 tint bin they have appears green tinted to some users. Others don’t notice.

I fixed my FW3A-SST20 so it doesn’t look green any more. I added a Lee 248 “half minus green” filter between the optic and the lens.

It’s a really nice shade now, but the lumens are even lower than the already-unimpressive numbers it started with. I measured three lights just now at the 1×7135 (350mA) level in my lumen tube…

  • XP-L HI 3D: 143 lm
  • 219B 4500K: 91 lm
  • SST-20 4000K w/ minus-green filter: 70 lm

The efficiency is pretty bad. 110 lm/W for XP-L HI, 70 lm/W for 219B, and just 54 lm/W for a rosy SST-20.

I also tried a Lee “quarter minus green” which would increase the lumens a bit, but I didn’t think the effect was strong enough… so I went with half minus green instead.

As a nice bonus, the pink filter is clearly visible through the lens, and it looks really nice inside the purple FW3A host.

So I finally have a 4000K light I like. Smile

I got some big sheets of the 3 most popular types IIRC awhile back, I will never use all of it.

Send me a message if you want some, I can sell a piece of each of them if you want.

I think I got them off amazon?
