its actually for out doors, like at night time. What it is, is 1 big ass 400 or 500watt blue spectrum CFL Bulb inside of a reflector, with the clear thick plastic in front of the bulb. It looks like a mini street light, except rectangle. I found it by going on Ebay and going to GROWING LIGHTS. Look throught them carefully and you will see CFLs for flowering and for Vegging. They run about $35 with $12 shipping costs. Look for high wattage, you should find it.
