Hello guys,

I'd like to buy a 600w hps bulb but I don't know what I have to choose.I have three links,maybe you can advise me ? by the way I need just HPS for flowering so a hps bulb with dual spectrum doesn't fit properly ? What do you think ?

ok so u have a 600w system

those bulbs unsure of ....never seen the brand
Hortilux
Ushio
Digilux

are the 3 well known brands that make good lights ............anyone of those will work fine for u the money might be a few more bucks but the lights are proven

if u want both lights hps and mh
u need a dual arc bulb ......but u need a 1000w ballast

Eye Super Hortilux is the best
Ushio is second

In the UK we don't have digi bulbs.

My advice for an HPS bulb in the UK.

POWERPLANT SUPER HPS

SYLVANIA GROLUX HPS

Sylvania grolux are my lamp of choice.

currently running the hortilux hps in a closed reflector in a 4x4 tent and an eye blue(mh) in an open reflector outside the tent. plants under the eye blue are more frosty than under the hps and the induction light. its not an apples to apples comparison, but w a staggered harvest i plan to give all the plants a dose of the eye blue before they finish
