Looking for a special plastic sheet

[fishgate]

I don't think it needs to be sealed. My ATI 60" T5 light just has a single piece of acrylic slid in under the lights and the frame to keep splash out. There is no sealing on it. if it is good enough for ATI it is good enough for me. I slide it out every month or so and clean the salt spray off it too.

all of my diy leds have acrylic splashguards. it only needs to be sealed if its gonna be like 2 inches or less off the water.

We're talking big tanks with big lights and big fish. My lights are 14" off the water and my tangs occasionally splash water on the barrier when aggressively feeding on food that is floating on the surface.

The cost of the added protection given by using a seal is minor ($20.00) when your look at total cost of an 8 foot LED lighting fixture. I'm glad I did it, I have peace of mind.

I run high voltage DC (100V) to a string of 33 LEDs (personal preference). That means I have zero tolerance for humidity (much less salt spray). So I need a seal.

The bendable plastic creates a contiguous surface that is easy to use with compression against the sides of the aluminum fixture.

Game changer! What I have done and recommended is NOT enough protection for your high voltage application. I defer to those with knowledge regarding the protection requirements given the high voltage and the environment in which it will be used.

Everything is grounded and on GFCI so it's safe, but any humidity is a problem. I seal it in a dry environment.

i would use a nick thick piece of acrylic (3/8", that's what I have on my 75 gallon setup, because why not) with a rubber strip around the edge and bolts holding it down. just like the lid of a calcium reactor. you could even put some color-changing dessicant beads in there. but yeah this is why I will stick to my eln-60-48D's. I dont have to worry too much about anything.

I found Lexan 0.02 film locally and that should work well.

I decided to make a 1/4" acrylic box first and see how that'll do.
