5.5W golfball In July 2017 I found this pack of three 470W 5.5W (85lm/W) non-dimmable nominal 40W incandescent equivalent golfball lamps for £5.99 in Maplin. (Back of pack.)

Given how some of our old Philips CFL 8W golfballs are fading, these seemed worth a punt, and at £2 each and reasonable efficacy, seem good value for money.

I quietly replaced a couple of the CFLs in the livingroom, and the 2W bulb in my son's bedroom which I am now finding hard to read by, to see if anyone notices! In the former, the instant-on of the LEDs is clear to me, and the remaining CFL looks a little sad; in my son's room the new lamp is clearly brighter and I'll just have to see if reading is easier on my ageing eyes...
