Great time for the Colossus

Prior to the rerelease of a limited number of Colossi a few weeks ago, collectors were paying top dollar for the very few that came on the market. Only 3 have appeared on eBay since 2009, one in the UK and two in the US with the most recent sold for $1500.00 with out shipping (estimated at over $400.00).

Now seems like a good time to start a separate group dedicated to this great work of art and other similar lamps. The most recent thread on OG has over hundreds of entries and is the longest thread ever!

Comment by Phishy Lava on April 15, 2013 at 9:16pm: This is the most 'action' I ever get out of my Colossus.

More than a little disappointed.......

Comment by Tim on February 18, 2013 at 9:01am: I wonder if its ok to use a 250 watt non BR40 bulb? I got a bulb that looks the same but the numbers are 250R40/HT Westinghouse and it was 4 dollars cheaper.

Comment by Kirk on February 18, 2013 at 3:53am: Nice mods. What is the model number/description on the 300w bulb you are using? I'd like to pick one up.

Comment by Jethro on February 18, 2013 at 12:29am: A few pics of the modifies lamp...I put multicolored lights in the cap:

red

blue

Comment by Jethro on February 16, 2013 at 12:26pm: A 300W bulb helps it warm up faster...mine will warm up in about 5 hours in a 60-62 degree room. It also creates bubbles of hot water that flow inside the goo. They reach the goo surface and pop or escape the goo intact and rise quickly to the top. I dont use 100% power very often except to warm up in a hurry. I've been researching transparent goo in order to see the bubbles better. It adds another interesting dimension to the lamp. I've also tried some experiments with my 300mW laser...it can pop bubbles!

Comment by Gwen Williams on February 16, 2013 at 11:57am: I ran mine for almost a week at 50-60%

Comment by Tim on February 16, 2013 at 10:33am: My 250 watt bulb seems to work just fine! My lamp has a amazing flow at about 60-100% range on the dimmner. How long can you run these lamps at one time? Is 24 hours to long?

Comment by Kirk on February 14, 2013 at 3:18pm: Still playing with the 250 and the dimmer. What happens for you with the 300? I ask because in some of my cycles with yellow/purple, I'll get the wax stuck at the bottom after about 10 hours. Autumn didn't think it was heating and that it just needed to be cycled (china wax). Wondering if 300 watt might help break it in faster?

Comment by Jethro on February 14, 2013 at 2:43pm: I've been using a 300W bulb with some interesting result. Anybody else tried something different?
