Grolux Lamps

SKU# G12

Grolux - WOW - great result Written by FDR \| 5 Sep 2012
Friends had told me that Grolux lamps really worked. I had always used the more expensive types, but needed some savings - so we gave Grolux a try. Been over 18 months now - still great results. Very pleased and would recommend this to all growers out there! Great value for such a performer.

hi please can you tell me the lumens output of the 250 Watt Sodium Grolux and will it work ok with the 250w Maxibright DigiLight ballast thank you for your help

The 250 Watt Grolux will give out 37000 lumens, they will work well with the 250W digilight ballast.

Can this lamp be used with the lumatek "super lumens" switch?

These lamps can be used with the Lumatek ballast, the super lumen swith will work with any HPS bulb, we would not recommend using the Super Lumen switch with a metal halide bulb.

Can I use a 600W bulb with a 400W ballast?

We would stongly advise against this, as wither the bulb or ballast will fail.

Will this bulb fit your budget/hobby reflector ?

The hobby reflector will fit any of our sodium or metal halide bulbs. You would need to fit an IEC plug with a 16 amp fuse if you want to use 1000 watt bulbs.
