replacement bulbs for grande

I just found out that you can no longer purchase 100w r20f in the USA! I was told they are all switching over to halogen or LED instead. I have a grande that I just restored with a kit, but I don't have a 100w incandescent r20f. I asked at Home Depot and Lowe's about the equivalent heat output for a halogen, but the people had no idea. :( Does anyone know what size bulb I should get now? I purchased a 60w halogen flood r16 and a dimmer, just in case it is too hot. But how do I know if the lava isn't flowing because it is too hot or too cold? Also, one last question. How long should I leave it running before it starts to flow?

Thanks

I've noticed that with my goo kitted grandes, which I've done about a half dozen, it takes a good 6 hours for the first couple times before it flows right. After that, about 3-4 hours to get her going, and then I have to use a dimmer to lower the power. I've never run into too hot on my grandes, but a good indication of too hot is the lava sitting above the coil versus around it. Also the grandes I have in a bunch, versus the one's standing alone with no other lamps, the heat up time will vary. I've wrapped my colossus in a blankie for about 6 hours to speed up the flow time. Be patient with the new grande you gookitted. As long as you followed the instructions, all will work out. Worth the wait!! :-)

As for the bulbs, online seems to be the best place to find them in quantity and at a great price. No particular place, just search for 100w r20 bulbs and a mulititude of site come up. I just stocked up on 100w r20's and the 40w r15's as I'd hate to run out, and I have over 100 lamps to power.

You might be able to use a 75 watt r20. The blue/yellow below is running one. Not much flow, but you may have better results if you are using a gookit.
