Need help with 600 W Lamps

Hi to all.

So i need to buy a new light but i need it to be a 600W dual, so i can switch between HPS y MH.

can any one recommend brands, Web Links , Anything

Thanks

Any digital ballast can run both lights. I like Lumatak or Quantum brands.

I'm not sure what you're saying, do you intend on using the Dual Spec for vegging (in place of MH), and then use HPS for flower?
My favorite brands are 'Sun Master' (MH, Dual Spec) and 'Osram' (HPS).

As SSHZ said Digital Ballasts can run both MH and HPS so check one of those out, because you will love the results you will get from MH
Lumatek is really good and is what I use.

Cost's a lot but worth it in my opinion are Hortilux. Highest lumen out there per watt and I have never had a bulb blow.
