what you need to do is go to littlegreenhouse.com they have a large selection of 40W bulbs, 105W bulbs with reflectors, or the 125 and 200W CFLS for a reasonable price (thats actual wattage), they also have the mogul adapters or prewired sockets for a decent price...i plan on getting 2 of the 125's for a clonebox with the prewired sockets they show the color temp there and everything hope that helps. if you have a socket go to 1000bulbs.com
