Hi,
I was replacing a G24D-3 fluorescent lamp in an outdoor light, and a label on the light fitting stated the lamp type was a 26W G24D-3 lamp, however I noticed the ballast had 18W written on it for the lamp wattage. The lamp fitted was a 26W one, and the replacement I was going to fit is a 26W lamp. It is worth noting that the light fitting has worked for about 10 years with the same 18w ballast with a 26w lamp.
My question is whether I should actually fit a 18w lamp despite the 26w rating on the fitting, or is it OK to use a 26w lamp even though the ballast is only rated at 18w?
Also if the combination of lamp and ballast is wrong, why has it worked normally for such a long time and without any obvious signs of overheating or anything?
Pictures attached below
Thanks for any help
