Just wondering if anyone has any experience with the Philips Ultralumes or Agro-Lights. I have 4 4-ft Gro-Lux Wide Spectrums (couldn't justify MH) right now, but I would like to add two more lights for a total of 240 watts. I was considering 4 Agro-Lights and 2 other lights to balance the spectrum a little. Thanks in advance, Roni
