Gear compartment: ballast clearly seen, alongside the ignitor and capacitor. The wiring reminds of semi-parallel method used by Philips, wires are quite thin too. Gear itself looks like it is not humid resistant, and would probably burn out if the upper plastic cover would be blown out, however that is likely impossible as the whole fixture would open up.

My idol is Mylene Farmer, deal with it.
New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
