E-ballast: OK to connect just 1 tube?

[stocker]

As above, if a 2x36W or 2x20W eballast connect just one tube, is it OK? and will it consume the same amt of electricity?

[nleong]

it may not even light up. If I'm not wrong you might have to do some tweaking.

Why don't just go for 2 tubes... solve every problem.

[stocker]

It can light up, no problem at all. Just want to find out if any ill-effects...

[tawauboy]

no problem. unconnected part will consume negligible amount of power. so if you are using 2x40w e-ballast to drive a single 36w pl tube, the power consumption will be 36w.

OK thanks Thomas!
