Question about light souce

PL_ · 22nd April 2005, 09:04 PM

Hi guys,
I am just putting some numbers together so my DIY project is, well, not even a project yet. Surely you can help me with this question.

Do you think this light source would be good enough for a 7", one mirror assembly projecting a ~70" image in a dark room?

Would you recommend any other?

And about the ignitor .. Is the power and type of lamp the only two technical things you should know when buying?

thanks

Thanks for the answer dj_holmes.

I don't mind sacrificing lamp life time for a smaller set.

But you are right, the kit from exclusive-online looks good.
I bought the optics there, I guess I'll have to pay the shipment again.

Anyway, thanks again.

Go for the osram 250W UVS daylight, you should find it at your LOCAL illumination store easly. They will order it for you if they dont have it, along with the ballast and ignitor. No need to order it online. Those lamps are very common, not like optics which are very difficult to find in retail shops.

That lamp has about 12000h lifetime and costs 60USD more or less.

Good luck with your project.

Who is this "bruv" person I keep hearing about? Please explain what that means.

Local slang for pal/bud/etc. I'd bet.
