I can recommend the LunaSea Lighting
I have installed 4 of LunaSea 4-bulb CCFLs three months ago, they work well and consume little power and are much cheaper than their competitor. They replaced 6 halogens, provide much more usable lighting
at a fraction of the power consumption
They now offer 2 different color temperature bulbs - a bright white 4200K and a softer cozier 3000K for the salon
The 4200K bulb at full intensity provides a superb light for aging eyes to work under.
The company has to date been exemplary in its support of the product - I cannot praise them enough. The lights and their supporting circuitry are designed by them. Hence their technical support is so comprehensive.

They also carry a host of other products of which I am unable to comment on as I have not tried them.
I have absolutely no financial or any other interest in the company - I am simply stunned by their excellent level of support and after sales service
and besides, the product works a treat.
