Is it that far behind LEDs etc in terms of efficiency/life?

I've heard they are, but not having testd them myself I can't say.


A florry gives a more even illumination than a series of LEDs.

That's not really true espeacily over time, the ends of florrys go black and start to flicker and get dimmer with time.


Also a better selection of colour temperature, etc.

Not sure that is true, but it should be difficult for LED tubes to be desined like the phillips hues.

We have new LED tubes in our new lab auto on and off, in my office they are also dimmable unlike the florrys in my present office, one of which is just flickering. One in the corridor is flickering and making a noise.
It could wake the students up ;-)
