Learn something new every day i never knew 32 was 830!

TBH I didn't have a clue what 32 was when I picked it up, I got the info from Lamptech, very useful chart of fluorescent colour codes old and new

Im gonna have to dig my 2 2ft 32s out now

Colour 32 is a Delux halo colour, colour 830 is a Triphosphor colour it just so happens they have the same colour temp and CRI index but they are not the same (colour 32 is much older then 830)

830 is just a modern, standardised way of saying what cri and colour temperature a tube is, thus this tube is 830. It doesn't matter whether triphosphor or halophosphate, but yes this one is halophosphate deluxe and was known as 32 back in the day

my argument is, tube is not the same as any tube marked 830, when this tube was sold alongside 830 tubes it was still labeled 32 to avoid confusion with actual 830 Triphospher tubes, I say calling this tube an 830 tube would be incorrect, as while "830" is a break down of the CRI and colour temperature of a tube its also used as an identifier, a way to tell what type of tube a tube is, for example if we used the numbers your way, then someone could say "I have a 830 tube from 1968" which would just confuse most people as everyone associate 830 (or any 8xx) with triphospher tubes

Alright then, this is "low lumens-per-watt 830" lol. I see your point, me and you know this is Deluxe Halophosphate but Joe Public might not, and I guess if this was sold as 830, it could have been confusing. Not that fluorescent numbering systems are straightforward to begin with, hence I prefer to just say what this is in the modern way. From now on I'll point out whether Tri or Halophosphate
