I've looked high and low on the web and cannot find a replacement bulb for my colossus. The original bulb has been listed as R95-200W on some sites. There are no reflector bulbs out there on any light bulb site that are 200W with a MOL of about 5.2 inches.
I unscrewed the bases of the metal bulb holder and spread the base, drilled holes and screwed the base back together to lower the height of the bulb socket so I can use a 250W clear infrared heat lamp that has a MOL of 6.5". The "color" of the infrared bulb is about 2500, which is similiar to the original incandescent.
There's another thread which discusses MH as a possible sub. Trying to incorporate a MH bulb seems like a lot of hassle. What are my fellow lava peeps doing to address this issue?
