I'm using a 400w Grolux hps (58,000 lumens) and I'm really happy with the results. But mine is just a regular Grolux hps - I don't know what their dual spectrum bulb is.

the dual spectrums lumens is 58000 but it said that it has a blue spectrum as well i thought plants did better under an red orange spectrum in flowering ?

The blue spectrums are to help during the veg stage, it's added to the HPS red spectrum, no loss of lumens....

it's all good for the plants...both are great bulbs....enjoy.

I tried looking up the duel spectrum bulb couldn't find it, could be due to different continets!

Lets try this, I need the manufacture name, if a majoir manufacture there is a model number on the box. (ex. 400/mh/eco)

This will help alot then I can tell you everything about the bulbs.
