Hi why prefer this type of lamp with the ballast connected instead of the classic separate ballasts. Also what is the benefit of 400v over the standard voltage and how long ddo the lamps last?
Thanks

Hi GL, thanks for your question. This kind of all-in-one ballast/reflector is more convenient and compact, with less cabling involved, (No external lamp wires results in low EMI, which makes it easier to comply with FCC regulations.) but it's a matter of personal tastes and requirements. For example, if excess heat is a problem in your grow room then you may prefer to site the ballast outside of the room.
As for the voltage, this is from the Gavita website; "400V lamp technology for high frequency electronic ballast. The high voltage lamp technology results in a better efficiency of the arc tube: more light for the same power (10-25% more than traditional single ended lamps)! These lamps are best suited for extreme high frequency electronic ballasts, creating a stable arc without acoustic resonance, assuring optimal output and a long lamp life."
There's a reason why Gavita are considered leaders in this sector, they offer a very high-quality product.
I hope that helps. All the best and happy growing!
