Your beside lamp?
Ceiling lights?
Softbox?
On the presumption your query is in this section on purpose, then what power supply is your softbox supplied with?
That'd dictate the highest wattage lamp you can operate with it.
I've seen the 20+ watt versions (CCFL) on ebay - 4000ºK to 6500ºK
I just made a donkey of myself there didn't I?? Of course he's talking in a photographic context!!!
Failing that, go to ebay and use e14, daylight, cool white, ses, 4000K, 6500K, etc as search parameters. Restrict to UK only if you want to get rid of all the China sellers.
You ask for all this detail and tell him to get anything from 4000K to 6500K.. that's a massive range.
If this is for accurate colour rendition to judge prints by, then you need something with a high CRI (Colour rendering index). As for colour temperature, most print booths use D50 (5000K) lighting for photo work, and D65 (6500K) for pre press proofing. Personally, I prefer D65, as it's the most common white point associated with computer screens, and most calibration software uses D65 as a white point. No idea where 5000K as a photo standard came from, but it makes little sense to me.

Try this...
http://www.androv-medical.com/product/166/45-watt-screw-full-spectrum-daylight-bulb
That's a 6000K lamp with a CRI of 93.
Unless you're proofing for the printing industry and the rest of your work flow is highly managed, and you have Munsell neutral grey walls and zero ambient light from other sources...... that will do you.
Sure you want 40W though? That will be very bright used in an overhead fitting, and blindingly bright in a desk lamp.
