asked on

USB powered ceiling light-bulbs & fans ?

Is it a trend now & where can I buy USB powered ceiling
light bulbs (LEDs) & fans?  Ideally the electrician can design
or make a switch such that it could tap from the main utility
power or the USB batteries (will 19V suffice?)

Any links on where to obtain such items?

I don't like CFL's at all (takes long time to "warm" up, low light output etc). LED lights are now far better (lower W, more light), and most types now include dimmer compatibility (My whole kitches was bright at normal 400W total bulbs, now with cheap IKEA dimmable LEDs, only 35W total, same brightness)
Yeah, but the LED cost is still high compared to CFL.

Wouldn't recommend LEDs this year but give it a couple more and when they start getting price equivalent to CFL.

Depends where you live.

Where I am incandescents are NZ$2 and CFLs are $5.  LEDs are more and not standard store goods which the first two are.
