I've seen those lamps before in, but they are rare. Is it a BT-37? The ballast & cap are huge too!

I agree the 750w HPS Lamp is hard to find, I bought a Unbranded 750w HPS lamp off the US E-bay 2 years ago, see HERE for Lamp Etch see HERE, I have never seen any since.

That is one wattage I have wanted for a while.

Yes it is a BT37. They are rare but they have a use in some places that's why they have not been discontinued Wink

Hi Dave

Bulbamerica still sell the 750watt HPS Lamp see HERE however they aren't very expensive at $245.83

E-bay did have 4 for $50 USD see
HERE, the only reason I didn't bid the Seller only shipped within the 48 states in the USA.

Other US Lamp suppliers list them for about $70 to $80 USD

In the UK we can get a Tubular Lamp known as PSL ( Photo Synthesis Light ) for Grow lights I have one see HERE

I hate to Price the Ballasts for these Lamps

All the Best

Why do they make the HPS lamp's envelope so skinny?
Form109   [Mar 11, 2011 at 10:52 AM]
what is the purpose of 750 Watt HPS?...why not just use 400 or 1000?
mercuryvaporrocks   [Mar 11, 2011 at 02:11 PM]
750 watt HPS seems ridiculous to me.
gailgrove   [Mar 11, 2011 at 08:40 PM]
Then try to figure out 35, 70, 200, 310, 430, 600, they "could" all use the next wattage up and/or down but really whats the harm in having more lamp variety? 750 watt puts out about 110,000 lumens VS a 400 watt one which only produces 50,000 or a 1KW which puts out 140,000, 110,000 is the same as a 1KW MH so to me it makes sense Razz
streetlight98   [Mar 11, 2011 at 10:13 PM]
Yeah, but you register more of the lumens with metal halide, so it looks brighter Razz
gailgrove   [Sep 18, 2011 at 04:50 PM]
BTW Dave, here almost all the highmasts use 750 watt HPS lamps, so there are thousands likely tens of thousands in use here!

Yep I have a pic of a highmast fixture with some 75 tags on them.
