Gluing LED Lenses
 

I'm looking for something local I can pick up this morning preferably to glue my lenses to my LEDs. Lots of sites say Loctite is fine but don't use superglue cuz it will fig the lens. Most Loctites are Loctite superglue though. I came across this stuff too. What do you think?

Are you talking about the bigger secondary optics or the small dome shaped primary optics on the LED itself?

This guy right here.

These lenses are pretty old too. They were part of the original LED Group Buy in like 2011 I think. Are they out of date or is a lens a lens?

Secondary optics. Those are easy. Tiny dab of silicone on the edge where the plastic contacts the star/circuit board. It will hold them in place and is easy to remove later if needed. Glue them with the fixture laying on it's back, not with the LEDs facing down. Give it a couple hours to set. You'll be golden.

Oh, and a lens is a lens. They are fine.

Thanks very much. Any particular silicone?

gonna slap you :)

Lol Why?

Any silicone that comes out of a tube and dries. Unless you're submerging the light, then you want reef safe. It's just pliable glue in this case :)

Well there's all kinds of articles on what glue to use so you don't fog the lens. I don't know enough about silicone to know if it can be similar. Lol Better to be safe than sorry.
