I am looking to do a smaller grow, build a more concealed cabinet. I currently have a 400W hps and want to down grade to a 150W or 250W since I only have 3 plants and pretty small area about 3ftx1.5ftx4.5ft.

Can I use the same ballast reflector (the 400W) for a smaller bulb? Will using a smaller bulb help with heat?

Thanks for any help.
