Manufacturers/resellers of metal halide (MH) bulbs warn that most powerful ones should only be used in safe casings that prevent from possible bulb explosions and (most important) from UV radiation that all MH lamps produce.
I've also heard that UV not only hurts the retina, but it can damage equipment, i.e. burn out pixels in LCD.
How do you deal with UV? Are there any protection filters that effectively block out UV and pass all the possible visible light range?

the metal halide bulb i use from venture lighting has a uv filter built in, i beleive it blocks ~80% of the UV produced by the bulb.
Could you please provide the model and base specs of your specific bulb?
As for now, I think on buying the OSRAM HQI-TS 400/D bulb, does anyone know of built-in UV protecton for this model?

That's the problem !
For example, in the OSRAM catalog there's only one tubular lamp wich is UVStop (i want FC2 support) .
And it's a 250W : 'HQI-TS 250W/D UVS FC2' (20000 lumens, 5200K).
🙁
The solution : 'Glass UV shield' used, for example, in Metal Halid Projectors.

Where did you get the ballast for your lamp? is 150W bright enough? I am in search for 150W-250W double ended lamp and ballast. lamps seems easy to find but it is hard to find matching ballasts. Thanks!

Got it as a gear tray already wired up for about £32.
So far its bright enough for all the testing I'm doing. I am only aiming for about 70" so I should get away with using a lower lumen bulb than others, (its quaoted as 12,000 lumens).
