While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
9 watt led bulb equal to cfl.
Leds require less wattage than cfl for the same amount of light.
Some manufacturers claim the new led bulbs will last up to 25 years under normal household use but this is not proven.
Are led lights brighter than or equal to compact fluorescent cfl bulbs.
Led vs cfl brightness.
Philips energy saver cflni light bulbs can be used in surface mounted downlight fixtures and recessed cans.
Philips energy saver compact fluorescent non integrated cflni 9w pl s 2 pin base light bulb is ideal for use in kitchens and offices.
Brightness is determined by lumens.
Cfl light bulb wattage led equivalent wattage 20 watt 12 watt 15 watt 9 watt 9 watt 5 5 watt 5 watt 3 watt led equivalents to fluorescent tube lights led tube lights use between 40 and 50 less energy than fluorescent tube lights which is of course comparable to cfls that utilise the same technology.
It offers significant energy savings in a compact size and provides a soft white light.
Some cfl and led bulbs will put their wattage equivalents on the box while many don t so this chart should help give you a good idea of how bright your new bulb is going to be.
Using the conversion chart above find your led equivalent bulb which gives the same amount of brightness.
The trick is to understand the technology.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
For example if you are using a traditional incandescent bulb in the range of 40 60w you.
In short led and cfl as technologies do not have a difference in brightness intrinsically.
