OT:
I have a Shine 3, and you might like some PBT caps. Ones from Banggood are really cheap ($18 for an 87-key set) and are medium thickness; LEDs will shine through just fine. My Shine 3 is the Yellow edition with thick PBT, and somehow Ducky managed to make it backlight-enabled, as I can see them perfectly.
My recommendation is blank caps. Makes your board at least 1.3x cooler, and you learn to type better.
I type in alot of weird positions.. so not really ready for blank caps. The trick is not the thickness, but the luminosity/transparency of the keycap when light is applied. Yellow is too bling-bling to me. I want red keys, and maybe green for; (up,down,left,right) and (wasd). I wish there was a store where I could try tons of keycaps, and just know what I want exactly. I really like
this keycap set, but I know it isn't friendly with illumination because the keys look too dark. :/
I have the LED lighting on the lowest setting (5 levels of lighting) in that picture. It's not that bad, at it's highest setting it's blindingly high.
You could put some thick PBT caps on there and cover those nasty LEDs up! 
I love the LEDs, although it'd be cooler if they'd give up on white/red/blue, and just give customers RGB with a gray encoded dial to switch the LED lighting.. maybe I should write some code for that... >.> (NXP processors are both
cheap, large internal sram/flash, and have rather obscene MIPS.)
