We just went live with a new lighting site. Can you please take a look and let me know your thoughts. http://www.lajollalighting.com
its a nicely designed site. but i find that there is too much of white in the background. Since your site is all about lighting you can experiment little more without going over the top.
I'd adjust the contrast on the left menu. The difference between whites and very light grays will vary greatly between monitors and be near-invisible on some.
