Colossus Bulb Not to be found - Sub 250 Infrared?

by Stingraymb

Mar 28, 2010

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?

    Well, my metal halide substitute idea is canned if the base can't accept a MOL of 6". I can't find any 200W lamp with a 5.2" height.

    The best I can find is the Philips part # 145516, 175PAR38/HEAT/CL, which is a 175W clear glass infrared lamp with a height of ~5.3"

    As for normal lamp 150W is available in BR38, 5 1/4" height, but not 200W.
    Perhaps GE or Osram Sylvania may have something else, but not in Philips catalog

    I didn't realize it used proprietary lamp.

    Since you adjusted the socket maybe this will fit http://www.bulbs.com/eSpec.aspx?ID=13870&Ref=Reflector&RefI...

    I know it may be a joke trying but have you contacted LavaWorld about this ? Hopefully they can get the bulbs for the lamps they sell...but I would not count on it.

    Quick Update - The infrared heat lamp solution is working well, it has now ran for a couple of days. I ran it a little hot initially, but have since found the "sweet spot" and marked the adjustment knob and the base with a sharpie. My advice would be to start it up in the early am so you can tweak it during the day as necessary. When unsure/before going to bed, adjust it to the "cool side." Anyway, whenever I need a replacement bulb, it's now available for $8 at the local home improvement store and the life is rated at 5000 hours vs. 2500 for the original bulb.
