55w or 65w PC lamps

Some people say that there is no difference. There is, however, a big difference in price. Should I get 55w or 65w 6700k PC lamps?

What I read on ahsupply was that the balast drives the lamp and I took to mean that if you have a 65w light and put a 55w 6700 bulb you would still get about 65w out of it. I think I paid about 25.00 with shipping from ahsupply for my 55w pc bulb. They are not as big in diameter as the coralife 65w but they seem to work fine. I went the cheaper route myself. it put me a little under 2 wpg intead of over 2wpg. Plants did not arrive yet so I can't tell you how they work.---------------Mark
