LED sticker shock is mostly behind us. When Philips introduced 60-watt equivalent LED light bulbs in 2010, they cost about $40 each. Four years later, the price has fallen to $12 or less and consumers can choose from a light spectrum that ranges from soft white led lights china suppliers, similar to an incandescent, to bright white, similar to fluorescent.

Prices are still painful initially when compared with a buck a bulb for a 60-watt incandescent, but the energy savings and longevity of an LED can save about $125 per bulb over an incandescent, according to Consumer Reports.

That’s allowing consumers to focus less on price and more on function. They can confidently select a 60-watt LED equivalent that is dimmable, flicker-free, and pleasing to the eye. But consumers will also find LED versions of three-ways, 100-watters and fluorescent tubes that weren’t on the shelves last year. “This summer is a good time for consumers to discover LED. There are a lot of new options,” said Mark Voykovic, light bulb merchant for Home Depot.

Cree Inc. of North Carolina, one of the first manufacturers to sell LED bulbs for less than $10, just released an LED version of a three-way bulb (a 30/60/100-watt replacement) for $22 at Home Depot. The soft-white bulb can’t be used in dimmers LED panel lights ul approved china but is expected to last 23 years, using only between 3 and 18 watts.

“Cree is a reputable, relatively inexpensive brand that gets good reviews,” said Rob Jackson, an LED specialist at Creative Lighting in St. Paul. “It’s hard to go wrong with them.”

Last month Cree also released a Par 38 90-watt outdoor flood ($25) that’s a good replacement for any hard-to-access light. “It lasts a lot longer than the halogen, and it doesn’t attract bugs,” said Voykovic.



Philips just released an LED Slimstyle 60-watt bulb for $10 that weighs half as much as most LED bulbs. Its flat shape makes it ideal for table and floor lamps as well as pendants and sconces, according to the manufacturer.

Cree and Philips have also released LED tubes that replace fluorescents. Philips InstantFit T8 tubes are compatible with rapid-start and programmed-start ballasts but not older magnetic ballasts. “Fluorescent tubes are very energy-efficient, but the LED versions use only half the energy,” said Mike Connors, CEO of Bulbs.com.

One problem that LED technology has faced is creating bulbs with enough lumens or brightness LED panel light company. But newer LED versions of 100-watt bulbs have been released that sell for less than $25 and make excellent reading lights. “The color temperatures and brightness of the bulbs has really come a long way in the past two years. Very good products have gotten even better in the last 12 months,” Connors said.

But consumers still need to read labels and stick to reliable known brands, said Jackson. “There are noticeable differences in brightness and coloration among manufacturers,” he said. Consumers have to read labels for the warm or cold light (2700k is warm yellow; 3,500k or higher is brighter and bluer) and brightness (a higher number of lumens means more light). If a consumer wants a dimmable bulb and the label doesn’t say it’s dimmable, don’t buy it, Jackson advises.

Quality is improving but consumers are noticing differences in brightness and coloration. Consumer Reports gave top ratings to LED bulbs from Cree, Philips, Sylvania, EcoSmart, Feit and Utilitech.

In a recent article, I referred to a bicycle as an invention that has been around for more than a 100 years. It is still essentially the same - and that was a good thing led light supplier. There is another invention that has been around for the same length of time - but that is not so good. It's the humble incandescent bulb.

Till fairly recently it has been the primary source of electric light. However, over the last few years, other options have emerged - namely Compact Fluorescent Lights (CFL) and Light Emitting Diode(LED) bulbs. The question then arises - should one switch to using the other types of bulbs? The aim of this article is to analyse the numbers in order to see what is the best option. The quick answer is that LED bulbs are clearly the best, but if you would like a more detailed explanation, read on.

A little bit of history

The invention of the bulb is usually attributed to Thomas Edison and Joseph Swan - but was actually done before them by several other people. However, they were the first to T10 LED Tube Lights commercialise them. Edison and Swan's early bulbs used carbon filaments. The bulb in more or less its current form, with tungsten filaments, was invented by the Hungarian Sandor Just and Croatian Franjo Hanaman in 1904 - a 110 years ago.

Perhaps because they were cheap and electricity was not too expensive and plentiful in the West, no substantial changes were made in the design of the bulb for several decades. It's a bit shocking when you think about it - the bulb in its current form existed before the car, radio, TV, airplane and any other form of technology that is commonplace today!

The fluorescent light has been around for quite a while, invented in the late 1890s by a gentleman named Peter Cooper Hewitt. The CFL was invented by Edward E. Hammer, an engineer working with GE, around 1973. However, it was only after 1995 that they became commercially available and started being used on a larger scale. In many countries the sale of incandescent bulbs has been banned, thanks to the availability of cheap CFLs.

The red LED was invented by Nick Holonyak Jr. in 1962, while working as a consultant scientist for GE. Prophetically, in an article in the Readers Digest in 1963 itself, he predicted that LED bulbs would replace incandescent bulbs. So while Edison - though he is known for it - did not invent the light bulb, the company he founded, which made him a very rich man, has played an important role in the development of bulbs ever since.

The problem with incandescent bulbs

Incandescent bulbs are bad from many angles wholesale T5 LED Tube lights. They are inefficient: as is evident to anyone who has tried to study using a 60W bulb in the summer, much of the energy is released in the form of heat. So especially in here in India, where heat is a problem, it is not a good thing. They do not last very long - most burn out within a year. The primary reason that they are still popular is that they are cheap to make and buy.

A comparison

Let us compare both the advantages and disadvantages. The primary advantage of the incandescent bulb is that it is cheap to buy. But in the long run that is certainly not the case. For the purposes of simplicity of calculation, we assume that the average house has around 20 bulbs of 60W or equivalent and the cost of electricity is around Rs 5 per unit. Further, we assume that these 20 lights are on for about 3 hours per night.
