Ah.. Yes then you need to get a new light. depending on your budget & what not. I would use the cfl & the 400 for vegin & I would pick up a 1000 watt for flowering.
Prob cost you about $200? You can get them for less if you look around.
Its IMO the most cost effective lights you can get & I know the product is better under them that the CFL's Never used the new induction lights or the LED's but I like to use what works & experiment with other stuff. I know the HPS lights work.
Good luck!
