Recently I noticed that the picture on my Evo 1.1 was starting to get dim, so I figured it's time to replace the bulb. The problem is, I'm unsure of what type of bulb I need to buy to replace it. Has anybody replaced a bulb in the ballast included with the projector, and if so, what did you use?

Google search of the LL Forum: site:lumenlab.com +evo +1.1 lamp OR bulb
Here's a link to the LL Store's Lighting section, where you'll find eVo lamps and ballast. I'm not certain but I think the Evo 1.2 Replacement Lamp listed gives you a choice of both types of lamps. It doesn't show that the items are out of stock, but it'd doesn't seem to allow you to order, either.
