are all high pressure sodium lights 2700k spectrum?

As far as I know HPS are 2700k only. I have atleast never seen a bulb with other spectrum then the before mentioned one.

 

[bonsai]

Definitely not. I have an osram here that's rated as 1.9K, and I'm pretty sure their NAV range is 2k

Nope, they come in all sorts of "tuned" flavors.

^yep. I like the full spectrum ones

 

[Scrogerman]

No! check product specs!

Low pressure sodium, NOX, comes in about 2K. I keep wanting to use one as they are even more lumens per watt than HPS. I mounted a 500 watt NOX on a hanger pointed at the fuel pumps, it lit up (to my eye) about the same as 3000 watts of MH. Holy lux, it is bright, but every source and anecdotal story says these lights absolutely will not grow anything whatsoever. I wonder if it is because these are a single frequency light? is 2K is so cold not even enough red comes out?
That 1.9K spec from Osram made me think of these.

1900 to 2200k are the numbers ive always seen.
