if your using a 12- 15w CFL or a 60w incandecent bulb you can now replace these with 6w 240v LED globes, this will use 10x less power than your incandesent and half the power of your CFL bulbs, with light output higher and a whiter with more natural daylight light, they  and not emit uv radiation which is what yout suntan bakery is doing but in a smaller form of a CFL, lets see 50000 hours is 2083 days 5.7 years i will not be changing that light bulb, as i have just retro fitted my house with these and i am pleased with the results, but there not for everywhere, i still use 3 cfl's 1 round tube for the kitchen and 2 dimmable cfls on dimmer switches for lounge, these LED globesare good for spots, i use 2 in spots for my dinning and i find it enough light to see my dinner, they also give off no heat , i used one in a kids night light that kept getting to hot and dangerous, i now feel safe to leave this light on for long periods with out having to worry about a fire,
