nbd13 - Hi Newbie; welcome to the forum! I got a four foot/four bulb T5 set-up, bulbs included for $160. No tax but I did pay $20 shipping. I found others that seemed cheaper but the bulbs did not come with it and they are about $15 a piece. I like the quality and I am so happy with the results I can already see in my orchids. Try

Button - if you are talking about artificial lighting I would use HID (expensive) or T5's (at least four bulbs wide) for high light orchids like Catts and Oncs.
