Glueing down optics for rebel LEDs?

[JFD140]

Ok so i have these optics holders from carlco

And they are getting fixed to a PCB. What is the best method of glueing these down?

I used silicone for my first board, not sure how it will hold up though.

Am i better off with a plastic cement?

as with everything at lights:
Epoxy glue!


advise: do not use Super Glue! NEVER!
when getting warm, makes smoke. Everything ruined

Hmmm I could do that... What about hot glue? Probably wouldn't sit flat enough though.

gets loose when hot
(have You ever used a high powered single led? Not to think of quads)
Hot glue is totally useless for anything (except quick repairs)

I have not yet found anything better than Epoxy glue (UHU Plus endfest - UHU plus very long time to cure),
something that gives the same results at those low price.
Its my "use it for everything"-glue

Silicone should be fine.

Silicone should be fine.

Holds well enough, but you can pry things apart when/if you screw up.

What type of silicone should i use? Do i want to buy the kind in a toothpaste style tube or use the construction stuff in caulking tubes?
