Development energy efficient light bulbs has been
advancing at a furious pace. This is because more people are aware of
environmental impact that non-energy efficient light bulbs are. Manufacturers have been competing with each
other to produce the most energy efficient light bulb that meets the
requirements of different people. The increase in the number of manufacturers
working on energy efficient light bulbs like Light Emitting Diode (LED) bulbs
has had a positive impact, not only are there more choices on the market but
the price has been pushed down. There are three basic reasons that people
should consider changing to LED bulbs.
1. They are energy efficient which means they do not use as much current as incandescent bulbs
2. They have a wide application in most homes
3. They are cost-effective and cheaper

Initial reactions to LED lights
When LED bulbs first came onto the market there were a lot
of people who did not like how dim they were as well as how cold. Those first
experiences have kept some people away from LED lights but LED light bulbs have
changed. LED lights now come with different brightness and color and a range of
fittings.
Here’s a guide on how LED light bulbs have evolved and the
advantages for home users who switch to LED Lights:
1. The Lumens ratings
1. The Lumens ratings
The Simple light bulb has come a long way. Consumers now
have more choices like CFLs, Incandescent, Halogens and LED lights as well as
different choices with regards to size, shape, the bulb base as well as price. FTC come up with a ranking system to help make buying LED lights easy.
All light bulbs are required to be packaged with labels that
replace watts to lumens. Lumens are an indicator of amount of the light a bulb
can emit, it is the brightness of a light bulb You can compare the lumens or
brightness levels of a light bulb before you buy it. You can then compare the
different energy efficiencies that each type of bulb has and determined the
lifetime cost.
2. There is no Mercury in LED Bulbs
When the concept of energy efficient light bulbs was
introduced, it was the CPL bulbs that were delivered to the market. CPLs had
one drawback, it has small amounts of mercury which made them a little
dangerous when broken and make them an environment hazard when they are
disposed of. The issue of Mercury is confusing because despite the mercury in
the bulbs, manufacturers and regulators still reasoned that the amount of
mercury in CPL is not that significant to cause environmental problems. CFL
bulbs are still being sold as energy efficient light bulbs but for people with
issues about the mercury in the bulb have chosen to look at Led light bulbs
because they do not contain mercury. There is no potential hazardous condition
that can arise from the handling and disposal of LED bulbs.
3. LEDs bulbs instantly light up
3. LEDs bulbs instantly light up
CPLs and tubular fluorescent light do not come on
immediately when they are switched on. There is a hesitation before they start
glowing. LEDs come on in an instant. They do not flicker, or appear to be
trying to warm up when they are turned on. The light does not flicker. In the
past LED lights could not be dimmed but now they have been designed to work
with light dimming switches. LED light bulbs lose their brightness over time
and will emit a low light. This is a useful indicator for when consumers need
to start thinking about replacing their bulbs.
4. LEDs reduce the interior heat input
LED lights produce a cold light. Normal incandescent light
bulbs can emit a lot of heat. LED bulbs release a cold light, which is great
for people who live in warm climates like Singapore. To illustrate:
A 100 watt incandescent it puts out 100 Joules of energy per
second. In a room measuring 48 m³ one 100w bulb can raise the temperature by
0,00170C/second. This means that in one hour, the room’s temperature
will have risen by 60C.
LED bulbs are designed with aluminum struts around the bulb
which acts as a heat sink to keep the temperatures low. LED bulbs by any
measure cannot contribute to the buildup of heat which ensures a cooler
interior.
5. LED bulbs are UV free
A lot of the LED bulbs do not emit ultraviolet light like
most other bulbs. UV light attracts moths, mosquitoes and all those insects
that come out at night. This feature is not available in all LED bulbs. There are special LED bulbs that can be put
outside that will not attract insects that are commonly attracted by white
light.
6. Know the difference between UL (Universal Laboratory) compliant and UL Listed
6. Know the difference between UL (Universal Laboratory) compliant and UL Listed
Most LED bulb packages are marked either with UL listed or
“UL” Compliant. The UL Listed label refers to bulbs that were manufactured
using UL guidelines. These bulbs are then given a UL listed mark which means
that they were created under strict conditions that ensure quality product
tests. UL compliant LED bulbs are bulbs manufactured in accordance to the UL
guidelines but the manufacturing process and the testing might not be as
stringent as that prescribed by the Universal Laboratory.
Unfortunately as the LED market grows and demand is on an
incline as it has been a lot of manufacturers will claim UL listings or
compliance to sell their product. There might be a price war but as a consumer
you need to weary of products that are ridiculously low and make outlandish
claims. Quality products might be slightly more expensive but it is worth it. A
quality LED bulb will last long and give you real value for your money.
