I suppose these are sold as an alternative to t5s.
slightly more lumens output for the same wattage - 17000 lumenns from 220 watts - but much more compact than an equivalent t5 fitting - less than half the size.
I have just bought a couple of fitting to try over my seedlings - not exactly these, must similar -

I have Philips horticultural pl-l 55w tubes to go in them.
Does anyone have any experience of these lights?
