Incandescent bulbs - Lumen output ?
Can anyone tell me what the typical lumen outputs of "normal" mains
40W / 60W / 100W bulbs are or a website ?
Also what the typical light output reduction is with age of the bulbs ?
Be interesting to know how the CFL outputs compare and how different
manufacturers products compare (e.g. Mazda / Osram etc )
Thanks,
Nick
