A lightly frosted glass diffuser on the light. A brushed reflector rather than mirrored reflector in the fixture. And bigger distance from the fixture and the tank. And also a fan.Back to a very interesting subject here...
What materials could we use over the plastic frame to avoid such damage?
Anyone?

Hi everyone
U guys r funny
I light my 250 reef with just two 6in candles. And wow the sps just love them there growing like crazy
And there very cheap
I was referring to anything that we could put on the plastic to protect it from happening...A lightly frosted glass diffuser on the light. A brushed reflector rather than mirrored reflector in the fixture. And bigger distance from the fixture and the tank. And also a fan.

Perhaps an aluminum cover?
Thanks.

I would fix the cause rather than the symptom.I was referring to anything that we could put on the plastic to protect it from happening...

If it’s meting the tank , IMO , it’s an indication the tool is being used improperly or is a poor tool in the first place. The same would be said for most of the issues I see with leds.
Most would say to use two Kessil 360 pucks as they produce enough par , but that is two spotlights , I would use four 160’s or four 360 and just dim them.
The same could be said for MH as well , depending on the fixtures , 2 250 pendants or four 150 pendants.
Myself , I would choose the latter.
Better coverage for one , and better more even dispersal of IR so it's less concentrated in one spot and melts things.
The light.Which "tool" are you speaking of? The light or the frame?
God I love arc lamps.
Wow, nice bulb!
That must be a huge tank!!! ;Wideyed

Yea it’s pretty big tank.Found one on sale for you..

12000W a lot cheaper.. Rated 150 hours.. LOL..

Hehe... That's a nice job that you've got!Yea it’s pretty big tank.
And no , don’t worry about the price.
Lol
I was thinking of removing the central part of the plastic brace from the 75gal. and replacing it by a 6" wide glass. I would also put a 2" wide glass on each side of the top when having halides next time, with the total of 3 glasses. Thickness would be the same as the tank which is 1/4".Fans have always kept my tank lids cool. One of my friends used to wipe 303 Aerospace on his plastic. The problem is cheap plastic or too much spill. The corals really benefit from the UVA, so I would not try and limit it too much - the glass in the fixture will take care of the harmful UV. The heat is not the problem if you manage it, but this is true with almost every problem on the planet.
Lets don't forget that in an integrating sphere with a 40K spectrometer, the 20K Radium and 14K Phoenix put out the same ratio of radiated watts (within 1%) as a Gen 3 Radion did and 40% more than a Kessil in the 350 to 850nm range (we took out the IR over 850nm). I wish that we could have measured T5s, but they did not fit. The only way that one is more efficient than another is to only measure part of the spectrum with an inadequate tool. Again, why sweat the details... they don't matter at all if they don't tell the story that you want.
Has anybody here even had their hands on a 1000W aquarium MH bulb? They are not that big, but they are impressive.
