[VapedG13]

Got a question for anyone.....I usually use a Sylvania MH bullb its about the size of my head:D

I bought a 6 pack of bulbs off ebay they are smaller sized 1000 watt MH bulbs but still put off 110,000 lumnes.... cost $125 for a 6 pack of bulbs:thumbsup:I normally spend $50 on 1 Sylvania

My question has anyone else bought and used this sized 1000 watt bulb??

They are both large mogel base and use the same ballast

They should work fine but they are a little week in the lumens. The growbright 1000w I buy are supposed to be 155,000 lumens. If you can believe what they say. Personally I plan on buying a 200,000 lumen light meter and see if they really put out what they say they do.
