LED Light Bulb Reviews

This article was written by Frédéric Wetzel*

In Switzerland as in France, thelighting accounts for nearly 15% of electricity consumption , but this expense can be greatly reduced by using efficient bulbs. At home, I adopted quickly CFLs then the first LED say classic a few years ago. Permitting these bulbs to achieve significant energy savings, new generations of so-called LED power LED would seem to be even more successful. So for the same amount of energy consumed, according to the manufacturers, a power LED, can emit 10 times more light than an incandescent bulb . But these figures are reliable? Are these bulbs really efficient and effective? To check, I tested myself these bulbs and I am pleased to present the results I got on the ecowizz blog!

LED Light Bulbs

My installation and replaced lamps!

This is what it is possible to replace any type of LED light sources?

From now on, we can answer in the affirmative. In fact, for a long time, it was very difficult to find LED bulbs equivalent to incandescent to high power (60 W…). But now, these bulbs are becoming very frequent and even large manufacturers (Osram, Phillips, Toshiba…) offer. From my side, I was able to find bulbs screw (E14 and GU10), bayonets, but also LED neon bulbs or GU10 and MR16 spotlights. Living in France, I bought my bulbs on the internet in a store (ecology-shop) online. In Switzerland, there are also online shop offering LED, this is particularly the case of MyLED.ch (see article by Cyrille: answers to the questions you might have about LED lighting ) !).

The evolution of my installation and savings I made!

Conclusion

LED near my front door.

Before the installation of the LED next generation (power LED), I had already relatively efficient bulbs (CFL and LED bulbs older generation). But the measures show that the new generation of LED are still more efficient (consumption divided by 3). Concerning the quality of lighting, I feel I have gained in brightness in the garage and in the driveway. For other parts, I would say that bright performance are equivalent, on the other hand, the LEDs offer a comfort to CFLs (immediate ignition…). Side finance, I believe in a rough way I’ll make my installation in a little more than 3 years. On your side, if you want whether it is cost-effective to replace your CFLs or incandescents by LED, I highly recommend the small program below that is very well designed: calculate the profitability of purchasing a light bulb, LED through the program Myled.
