I am looking for a lamp that is compatible with the Genesis 105W F73-T12-HO-105W Rapid Start RDC. I recently tried A Voltarc F73T12/HO/Classic which is compatible but just doesen't get the results. Could someone give me the magic answer. Thanks in advance??

There are plenty of great options. Try the Cosmolux ESP, Wolff Dominion, LSI Midday Sun, Philips Advantage, or Cosmolux Cosmosun 515.

I'm sure that there are many others but it is always good to stay with a major brand name.

YEP, those are good ones. Also check out Raddiance, marketed by 4 Seasons. I've used them in 2 of my beds that had Genesis 105's and the clients are really happy with their results. Price is significantly less than the Genesis also.

bsmart,

The Radiance line from 4 Seasons was made by LSI. They have recently switched to Voltarc, & are no longer carrying the LSI made version. So, you may want to try them again.
