Glo Lux is again one of those specialist tubes that doesn't strictly conform to a single Kelvin rating. It might have to be rated at around 8500K but again is a specialist tube.
Great for Hygros and some Dutch tanks, but they won't beat powerglos. Only tube that will beat powerglos are plantpros but at $120 per T5HO tube, I wouldn't go rushing to the shops to buy them.
