Impossible to buy a bulb at random, banning incandescent models complicates the choice in store. We must choose between fluorescent compact, LED or halogen. The units, forms and powers do not facilitate the task. Our tips for buying that suits.
LED bulbs are multi-purpose, they either agree to all parts. They light up instantly, support the repetitive ignitions, can be used outside without any problem, even in winter. They consume as little as the neon compact, without their drawbacks. That choose has long discouraged them due to their prohibitive prices, now it’s over. Rates have fallen dramatically, LED easily pay for themselves in light of their life.
There’s the choice in store for common lighting, down to 1500 lumens, equivalent to 100-watt incandescent bulb.
Low electricity consumption
Suitable for all uses
Lack of profitability when the price is prohibitive
Risk for the eyes with some models
In order to limit the risks associated with the spectrum blue LEDs, toxic for the retina, prefer the bulbs with an opaque glass. If the LED is apparent, put it in a lamp with Lampshade or non-transparent walls. Thus the spectrum of blue light will be more diffuse. If you don’t have a filter of light (shade…), place the bulb to more than a meter from the looks. Same device for the spots or other lamps which light output is directed.
The Neon Compact
Also known as light bulbs low consumption. Compact fluorescent lamps have been badly loved for their light cold white and their large formats, but these teething problems belong to the past. Most offer a warm, light identical to that of incandescent bulbs, and formats have proliferated, you find everything, from the reduced to the traditional form. They consume little, five times less than incandescent bulbs, and generally last a long time, they pay for themselves so quickly enough to use.
The more difficult it is to find the neon compact ideal. She turns on instantly, fits all parts, including if the lightings are incessant, and holds the lifetime announced. Some combine all these qualities, but that to choose tests performed in the laboratory prove that this is not the case of all models. Some lights after 15 or 20 seconds, it is not tolerable anywhere, or do not support the incessant ignitions, then they let go too fast in a place of passage. Choosing the compact neon right is so delicate, so read the directions of the packaging carefully.
Low electricity consumption
Unsuited to the cold, avoid outdoor winter
Slow ignition with some models
Ignitions/extinctions cycles limited with some models
This is the improved version of incandescent bulbs. The halogens are all too practical but they consume a lot, four times more electricity than the neon compact and the LED to light equal, even when they claim to be “eco halogen. They hold at least 2,000 hours, against 6000 hours minimum for the neon compact and more for LED, therefore change more often. That to choose tests show they are significantly more expensive to use.
Since the price of LED dropped and their formats are diverse, the bulbs halogen, eco or not, have more objective usefulness.
Suitable for all uses, inside and outside
High consumption of electricity
Cost of high wear
Low life expectancy
Beware of the LED Spots
In 2010, the national agency of health security (Anses) came out a report worrying about the risks of the LEDs for the eyes, and especially the sight of children. In question, their high proportion of blue light, which “leads to a toxic stress for the retina” especially for children, stressed the Anses, because “their lens is still developing and can ensure its efficient role of the light filter.” Added the risk of glare and Visual discomfort. Immediately, that to choose launched a test to evaluate the dangerousness of the LED. Conclusion, the spots with apparent diodes pose a real risk.
To note, unlike the spots, frosted glass or plastic, without apparent LEDs, LED bulbs pose no risk to the eyes. To be preferred the warm white bulbs, cold lights being richer in blue color.
The Lottery of the Life Expectancy of the Bulbs
Manufacturers do not have the obligation to respect life that they display, whether it’s their compact fluorescent bulbs or their led. It is an absolute aberration. He is so authorized by regulation to market bulbs that do not reach 6 000 h of life, while the packaging announced much more. Just that a compact fluorescent lamp in two reaches the life expectancy of 6 000 h to be in compliance with the regulations! September 1, 2016, this rate increases to 70% for this type of bulb. For LEDs, this rate is 90% since March 1, 2014.
The luminous flux, light that is emitted, is also allowed to decrease over time. From 6000 h, LED lamps are permitted to illuminate that 80% of what they promise. The allegations would be deceptive but acceptable according to regulations!
Industrialists have therefore no effort on the quality or production control. The regulation encourages cheating, somehow. For the consumer, buy a neon compact or an LED shows, so a real risk. The model can let go before the promised lifetime, unless the buyer has no recourse. That choose recommend buying expensive bulbs.
