Re: LEDs
Philips makes LED tubes with an even output. The quick option is to replace the starter with the supplied shunt and pop them in. You can modify the tube fitting to get rid of the transformer thingy (don't know the English term) That will save some extra electricity. LED tubes use 1/3 of the amount of Watts so depending on usage and electricity price it pays for itself.
