Need some help to mod MH

For those who have used metal halides on your tank, what do you guys use to make a light guard/shield? I want to try and limit the light bleed towards the front but I have no clue where to start.

I am using a FNI 70w fixture btw.


Just 1 more I promise......

Maybe something like this:

Maybe fab a "wing" from Aluminum so there is a quick cool down when the lights are off.

Have I got a thread for you! This guy has a number of great DIY ideas in his journal.

I made shields from acrylic I had on hand and sprayed with silver gray hammer finish paint I have on hand. It didn't cover completely and if I only did a more even job would look terrific instead of just acceptable. Me and glass wouldn't get along, not sure which of us would be the biggest loser. You can simply tape a bit of paper up to check how long the shields need to be and that doesn't actually look bad either when lit up.
