Use Of Led Bulbs
7 Answers
Hi
If I buy a light fitting & it says maximum 40W bulb, could I put say an 8W LED in it, which should give around a 60W normal brightness? So my wattage is much less than the limit for the fitting. Or is it not as simple as that? Any advice most welcome

Just to illuminate (ahem) further; Here's a Watt-Lumen conversion chart:
How Much Light Do I Need?
Incandescent Bulbs
WATTS Minimum Light Output
LUMENS
40 450
60 800
75 >1,100
100 1,600
150 2,600
More info: LED Lightbulb brightness in general is measured in lumens (not watts). Light bulb manufacturers include this information and the equivalent wattage right on the packaging. Common terms are "soft white 60," "warm light 60," and "60 watt replacement."
To save energy, find the bulbs with the light output you need, and then choose the one with the lowest wattage. You can also look for an ENERGY STAR qualified bulb that is labeled as equivalent to the incandescent bulb you are replacing.
(I'm in the U.S., BTW.
Most folks like the "yellowish candle colored" light produced by the venerable incandescent bulb... to replicate this in the LED, look for the "soft white" information.
Additionally, make sure you are not replacing the incandescent bulb in a fixture that is "dimmable". If you are assure the replacement LED bulb is compatible with the type of dimmer switch installed.
Finally, LED bulbs do produce a significant amount of heat... they just do it in a different way by running the heat through a "heat sink" at the base of the bulb and then it's dissipated. So... assure that part of the LED bulb isn't obstructed else the life of the bulb will be severly shortened. OG is correct in that the heat is less than that produced by incandescent but still significant...
