which acrylic filter out uv radiation better?

[LIM CHYE HUAT]

due to the glare from my metal halide, i intend to fabricate a cover using acrylic.

the hardware shop guy said got three type=>

1) clear,

2)semi frosted(a bit light can go through) and

3)totally white.

which type is the best when comes to filter out harmful uv radaition or all are the

same.

From what I have learnt, UV can only be blocked by glass so acrylic might not be that suitable

bro.. acrylic cannot take heat from MH man.. u need to find UV treated glass...

at the temperature that MH is giving out....

i think yr acrylic will nua in no time!!!!!

the whole thing will be soft....

can u remember yr technical in sec school????

we use heater to soften and bend acrylic???

if u wanna cover yr MH light.... as in side and top.... go for metal cover....

if u wanna shield the UV frm bottom... like Mr. Ervine say.... use UV glass...
