Do these hold up to heat if used on a lens that puts out heat?

Mine does get hot, I have it on my lamp now and the paper is very warm but not hot. My halgen bulb is about 9 inches from the paper though. It is not sitting right near the paper. I have had no problems with them melting in any way.

They appear to be alright with a spot but I am only using them with bright LED spots. Sorry. I don't mind testing it out though.

I believe so, but I can't say for certain. It seems to me that these things are designed for stage lighting, which are usually hot, right.

They looked like they would - they were professional gels. I was using them for an art project

I use them for my clamp lamps for my films and they seem to hold up to heat.

I've mostly seen these used on stage lighting, which is hot. Generally they hold up well, but they can warp and melt if they are pressed directly against or too close to a hot light. If they have a bit of airspace between them and the light they seem to do pretty well. But I suspect there is variability across manufacturers, and the darker gels will get hotter than the light ones. My impression is that you will see warping before they up and actually melt on you.

I don't know the actual temperature they can withstand but I've held them over the grill at 700 degrees while cleaning it and no problem whatsoever. In fact, afterwards I took the gloves off and went to put my cleaning brush up and it was so hot (I didn't realize) I would've burned my hand had I not dropped it. Didn't realize how hot the brush got with the gloves on. I'm all for them but don't quite yet have all the experience with them I'd like. Right now though, I'd say they're a no brainer.

I've had mine since Oct 2013 and they are still fine. They're sealed in a foil pack like hand wipes so they should last a very long time before they dry out. I'd guess indefinitely. Are you just using them on glasses? I bought them primarily for quick clean up of camera lenses, but we use them on regular eyeglasses, smartphone screens and laptop/monitor screens as well.

No issues for me with flare...if course if I am shooting directly i not the sun as with any lens its best to shade the lens ..I use a foldable reflector

These were not 'high quality', meaning that they can have micro bubbles and fractures and/or temperature stress. If you expose them to high heat and they have a flaw, it will break. The price of these dictates that the are not tempered, or anything else that would give reasonable durability and/or temperature resilience. USE AT YOUR OWN RISK.

I have had mine since last summer. Use them primarily to ride my old Harley D. I am very careful when exchanging lenses and thus far they have been fine with no obvious scratches. Don't pull on the rubber part of the nose piece when exchanging lenses just the hard plastic piece. I like mine as can change for various lighting days.

They do heat up, if you wamted to put them behind glass or something that would probably still be safe

Not sure how to answer this but I will try. Yes, all halogen bulbs produce heat. If the housing your putting these bulbs in are designed for the H11 bulb, then the heat will not melt the housing.

Yes. You can bake them in the oven to heat the glue. There are tutorials on youtube. But you must be careful with these not to crack the glass lenses they have. I did. Ended up buying a set with plastic lenses. Much easier to deal with.

I have had no problem using them on high heat. This is a fine set of cookware.

Yes. These have been through the high heat of the dishwasher dry cycle without issue.

havent had any problems with these. but condensation problems can be cured by taking a small drill bit an put two little holes in lowest part of plastic lens

I don't think they would withstand the heat. I no longer have the packaging to see what it says on the label though.

I works awesome for constant filming...in fact i am about to order my second set. the lights have handles on the back in case the unit gets hot...but so far i have never felt my units overheat. I have done lengthy filming and photo shoots...and they always work great

Absolutely! There is really no heat from these lights and they do offer much light. We do personal videos and use these light with other lights to help adjust our sets. Hope this helps!

Yeah. They come off. The lens was spotless. It holds up to 450 fps at 20 ft

Installed right and left headlights late summer (2014). So far, have not noticed any condesation inside lens. Only issue has been a bulb burning out (drivers side running light bulb).
