Adapt non-CFL-rated timer to operate CFL table lamp?

Can someone help me create a box with a relay inside that sits between, electrically speaking, a non-CFL-rated timer and a table lamp with CFL bulbs? Ideally the non-CFL timer which I have plugs into wall outlet, relay box will plug into timer, and lamp will plug into relay box. What spec relay should I use for a lamp with a CFL equivalent to a 60 watt incadescent?

The relay will need to be - rated for 0.2A, as steveastrouk points out - rated for 15W - rated for use with CFLs. The last part is probably the hardest to determine. I suspect the time-switch is rated as not for use with CFLs because of its switching behaviour, but I can't say off the top of my head whether commercial relays will act the same way- you'd probably have to check with the vendor. I suspect solid state relays (SSRs) may behave better because they won't suffer the physical properties of mechanically switching relays, but I can't be sure- again, ask the relay vendor.

most relays I just searched for need a dc current to operate the relay coil itself (I know there are ac models, I just cant find any... To use a dc one you'll need a rectifier (wall wart) to close the circuit - also hooked up to the timer output...then the relay would close the circuit for the inductive load.
Little PCB mounted relays are rarely AC coils. Try looking for industrial relays like the Omron MY24 series

or just about anyones "Octal base" relays

Nice, big, chunky, reliable relays ! I love 'em
only trouble with the big ones is they cost big dollars... :( You are however, correct :D

get a wall wart, (like a cellphone charger thing) when power is applied, the wall wart will put out DC to the relay, the relay will turn on
Any relay that can handle more than 0.2 A of AC load will be fine. Make sure the coil of the relay is mains rated too.
