Hello, i just purchased THIS BALLAST off of E-bay.
I have no idea what type of bulb to by for my new ballast.
Any sugesstions?
thanks

The M59 ballast would use a venture 400w 4000k T15 (601711) horizontal mount or a venture 400w 4000k t15 bu (601710) base up mount. at businesslights.com

I have a bunch of links to bulbs you can buy that will work for that ballast.

http://www.1000bulbs.com/product.php?product=8703 Good bulb although too big for the pro reflector.

http://www.goodmart.com/products/243714.htm Currently the best T15 bulb available that is for the M59. It compares to the LL T15 PS, although the PS will beat it overall. Works perfectly with pro reflector.

Currently the cheapest T15 bulb out their, no idea of specifications, and atlantalight doesn't know either.

A T15 USHIO bulb, relatively inexpensive at 40$, no idea on the specifics of it though.

Thanks alot for the fast reply guys. I was worried with my luck i purchased a ballast that wouldnt work for the kind of bulb we need.
i was looking at This Bulb but I think it is the wrong color temperature.
I have been using a 150w halogen light up intill now and i think the upgrade will improve my results
thanks for the advice everyone

the goodmart bulb is nice, i think ill upgrade my projecter with it. why do you say the PS will beat it overall

I was looking at This One do you think it would be a good choice?

I believe that BU stands for "base up" burning position and it is too large of a form factor. Ideally you will find a lamp with a T15 bulb shape, 4000K-6000K temp, horizontal or universal burn position and as many lumens as possible. If you cant find a T15 you can use either a ED28 or BT28 but you will have to find a suitable reflector other than the Lumenlab Pro reflector for these lamps. These sizes were once the standard and work well in projectors.

Whatever lamp you buy; if it has an M59 ANSI #, it will work with your M59 ballast.

Yeah, I'm also thinking of getting the http://www.goodmart.com/products/243714.htm Well Pulse Strike lamps generally reach max brightness faster, maybe a minute or two faster. But they are also more expensive, and require more expensive ballasts. They maintain lumens better also, something like 80% efficiency, around their, and the standard M59 bulbs are less, but that is over a LONG period of time, so assuming you watch the projector for 10hrs a day, you have a few years before you will see a significant brightness drop.

That bulb will work perfectly as it is horizontal burn, and its the regular length and diameter. Its the best option for those who already own an M59 ballast and don't want to upgrade to the M135 PS ballast, or e-ballast. Yeah, so the main reason the PS beats it is better lumen upkeep and faster restrike time, but its a relatively small difference if your not picky.
