I recall mine were 3000K when I tested them but I can probably pull one out for testing later to confirm this. Perhaps Venture might have what you're looking for in 4000K. They had a lot of rather unique MH lamps including those long life dual arctube lamps.
Ahh, the 1980s GE HID sleeve effect
, I'm not sure why GE actually made those sleeves in the 80s that listed all the HID types on it. Fortunately the 90s sleeves when back to listing only the correct source on it.
The "seller refurbished" on lamps is always funny too, how to do even refurbish a lamp.
