Can I have 6 off, 6 foot twin fluorescent fittings please? High frequency ones.
-Sorry, we no longer stock those.
Oh, how about a single 5' one then?
-No sorry, haven't got any of those either!
Oh, I'm guessing you haven't got any 250W MBFU lamps then (Mercury vapour)?
-Nope: but we can order those in.
So after nearly 70 years, the fluorescent tube is now obsolete
Rather sad: I've always loved the technology and was fascinated by it as a small boy and have enjoyed installing it in small factories, offices & workshops ever since.
Luckily, replacement high frequency ballasts and T8 tubes are still available, so I will be able to keep older units running for a while yet.
I can't get excited about LED technology- It just doesn't do it for me like fluorescent does!
All the best
Nick
