Different sized 1000 watt MH bulbs??

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

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 I normally spend $50 on 1 Sylvania

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

They are both large mogul base and use the same ballast

Model: MH1000/BT37/U/4K
Wattage: 1000 Watt Metal Halide
Lamp Base: E39 (large Mogul base)
Lumens: 110,000
Length: MOL 11.5 inches

..............anyone???

they should still work, i use hps 600's and ive noticed they differ in diameter from brand to brand, that sucks as far as lumens are concerned, my 600 puts out 90,000

They're fine. There are a few different shapes and sizes, usually the smaller 1000's are used for aquariums but it really doesn't matter. What spectrum are they though, that's the only question.
