Reflector Heat Shields

[@b$+r@c+]

I know the placement of a 'Reflector Heat Shield' is entirely subjective to the rest of the environment, but am curious to hear if anyone's using them and how effective they are. I have a height limitation, and can only continue the same room structure if I drop a few degrees.
I also wanna know how heat resistant they are...In the scenario of a failed exhaust would it melt or ignite?
How about a 'Light Diffuser'? any thoughts on them?

I suppose I'll have to find out for myself, but any input or advice is appreciated.

I haven't used a heat diffuser in years, a really good sealed hood setup is generally much better for most uses. That being said the last one I used was aluminum and it worked pretty well to keep hot spots from happening directly below the bulb and I really doubt that it would have ignited or melted. If it's metal of nearly any sort the whole room is going to burn before it starts melting.

You are talking about a device that looks like some sort of latticework or colander that sits directly below the bulb in the reflector and keeps radiant heat from doing a number on your canopy right?

I think he is talking about something else. I think he's talking about the 'pajamas' that fit around the reflector. Its supposed to reduce heat.

Ive seen a youtube video of them and the guy used a ray gun or some crap that measures the temp of the reflector before and afer and it worked. Crap if I know what the video is called, but you may be able to find it OP.

Thanks guys.

...Yeah, I was more concerned with the fire safety of the fitted heat shield, but was asking about both.

the top of my reflectors dont get hot at all so i dont see the point of them.

If you have a sealed duct setup insulating your hood with reflectix or similar will minimize radiative heat gains in your room. With a tight sealed system doing this dropped my temps by 2 degrees.
