LED vs CFL Light Bulbs

A quick comparison of LED and compact fluorescent light bulbs. I've been replacing burned out CFLs with LEDs around the house and they are OK, but how well they work depends a bit on the fixture. It's worth testing before investing (a lot). LEDs work best in fixtures where the light comes out the end of the bulb (like in a can light). However they work almost as well (very acceptable) in some other fixtures where the bulb is horizontal and light comes out of the "side" of the bulb. The LED bulb runs much cooler for the same about of light (for example a 12 watt CFL vs 7 watt LED). That extra coolness is heat you don't have to pay for your air conditioner to pump outside. For a given wattage, the LED produces much more light, so if you have a fixture that is maxed out at say 12 watts and you need more light, then 12 watts of LED will be much brighter than 12 watts of CFL. The LED bulb is supposed to last much longer than the CFL (15k hours total life is on the packages for the ones I bought) or 8x the life of an incandescent. So the bottom line is they should last a very long time (good for hard-to-reach fixtures). This house was built around 1988. The light fixtures originally had the circular 1950's style fluorescent tubes with starter and ballasts in them. They were dim, required frequent parts replacement and ran hot. I changed the fixtures over to screw type sockets (see video here on that    • Видео   ) and went to 3 x 12 watt CFL bulbs. Since then our electric bill has gone down about 20% and stayed there. We hope to get another 5% - 10% savings by changing to LED bulbs as the CFLs burn out. Correction from the video, we have 115 regular light bulbs, not 63! For comparison, my last smallish house had 44 light bulbs, but also used some of the 3 foot long florescent bulbs and I did not count those. 20140909: UPDATE-we tried the LED bulbs in the 3 bulb frosted glass fixtures and they are acceptable. Here is the video:    • LED vs CFL - Are LEDs More Or Less Directi...   It is a bit dark in the middle, but not as bad as I guessed. The fixture is much cooler to the touch. We will continue to replace the CFLs in all our fixtures with LEDs as the CFLs burn out. 20181111 Update: I work on and off in Thailand and over the past year I'd guess nearly 50% of companies have replaced their CFLs with LEDs. It's amazing to see how fast the adoption of LEDs is. They really do save money in primary electrical use and secondary (not heating up and using more AC). We compare LED light bulbs and compact fluorescent lamps (CFLs) head-to-head for brightness, efficiency, heat output, fixture limitations, and cost. Using real-world tests with a 12W CFL (685 lumens) and a 7W LED (600 lumens). We see why LEDs often look brighter despite lower wattage, and how their reduced heat output can also save money on air conditioning costs. We also cover practical issues like fixture wattage ratings, light direction, and lifespan—showing why LEDs provide more light per watt, last many times longer, and can make a noticeable difference on your electricity bill when replacing dozens of bulbs around the home. Whether you’re a DIYer, tech enthusiast, or homeowner looking to cut energy costs, this experiment will give you a clear picture of the pros and cons of LEDs versus CFLs.
