Tomorrow I will order a MH and HPS bulb. I can't decide which bulb to buy.
I already bought a sylvania grolux lamp 600W that is supposed to do vegetative and flowering but I'm not very happy with it and I want a pure vegetative and pure flowering bulb.

My ballast is 600W.
Can anyone give me some advice?

This is the only shop I can order from:
www.hydroponics.eu/lighting-c-24/lamps-hpsmhagro-s-41


I'm in a bit of a hurry to order tomorrow morning (12h from now) else it wont arrive in the next 2 weeks


Thank you in advance for your time

Any 600w mh/hps light will do the job. Iv used both Philips and Sylvania and they both worked great.

What did you not like about the Sylvania? ...I was thinking about buying one of those veg/flower bulbs. Whatever you do just make sure that your reflective device is making the most of that $#@ expensive electricity. I bought a $20 light meter from Ebay (LX1010B) and was able to fashion a cardboard/ reflective mylar reflector that put more light where I needed it than the POS reflector that came with one of those combo deals from HTG (the 3 year old ballast still working). Just make sure you put some metal top side to draw the heat away.

Most people in the forums and the guy in the hydro store told me that those universal (veg/flower) lamps are "ok" for both but wont excel in either and that using specific pure hps and MH would be better.... and btw the light from grolux sylvania looks just like a normal hps lamp, you cant see any difference with your eyes so I guess they are not ideal for vegging although they will do the job but not in an ideal way (at least that's what I was told).

What metal top to draw the heat away? The super spreader (link below)?
