It may be troublesome to be taught a brand new system, and because the new LED products make their manner into public fingers, it is going to be essential to learn to learn the packaging. It could appear odd {that a} new type of lighting would require new information, however even with the more and more accessible CFL bulbs the scenario is an identical หลอด Led Bulb.
CFL producers have circumvented the problem by inserting the old equal boldly upon the packaging, so that you see them say “60 Watt substitute” to make issues simple. The brand new system would require bulbs to be listed with lumens, not watts.
What’s a Lumen?
Lumens measure the overall variety of packets of light produced by a light supply, which is an advanced manner of claiming how a lot light a supply places out. We now have grow to be accustomed to measuring light by watts. The typical incandescent bulbs solely put out about 12 lumens for each watt of electrical energy they eat. In distinction, LED bulbs produce about 60-100 lumens per watt.
Substitute Values
Since LED light bulbs can generate many extra lumens per watt of electrical energy used, they’re considerably extra environment friendly. Figuring out that does not assist a lot whenever you get to the shop and take a look at to determine which bulb to get whenever you want a substitute.
A 40 watt bulb produces about 400-500 lumens. A 60 watt bulb generates about 800 lumens and a 100 watt bulb places out 1400-1700 lumens, give or take.
Figuring out the approximate variety of lumens for which to look will assist you keep away from taking home the unsuitable bulbs. For instance, when buying bulbs to interchange these in a chandelier that makes use of 25 watt bulbs, which coincidentally produce about 250 lumens, you wouldn’t wish to get 0.5w LED bulb simply because the form is true – that bulb solely generates 4 lumens.
Understanding the variety of lumens is crucial to buying the proper LED bulbs. Take a chart with you simply in case you encounter bulbs which might be solely marked in lumens, a coming pattern. Additionally, search the packaging rigorously – CFL bulbs packaged in a virtually an identical trend to LED bulbs, and you do not wish to carry home the unsuitable factor.
