Here are some more posts/article that favor induction lighting:  cheaper, are more efficient, and are brighter:

LIghting account for 25% of total electrical consumption in a building. It is cheaper to buy and maintain. Induction lighting 101. Induction lighting is actually flourescent lamp. But they fail between 10 to 20t hours. Induction lamps do not have electrodes. They could last for 10 years if they are used 24 hours. They would last 20 years if used for only 12 hours a day

Induction lighting principles from You tube

 An induction lamp is actually a flourescent lamp without the electrodes. It does not therefore have electrodes that corrode or malfunction, or future leaks of gases.  Both though have mercury pellets that when excited by elecromagnets emit UV rays that strike the phosphor that emit the light.

Let us see more comparison between LED vs Induction Lamps.  Who do you think wins?







Induction lighting is based on Tesla discovery that elecromagnetism can induce the production of light

The most energy efficient and long life lamps are undoubtedly LED lamps and induction lamps.  Thus they are the desired retrofit for large area and outdoor lighting:  park lamps, street lights, and other types of lighting that require less change and maintance (those that are difficult to reach as in high ceilings or lamp post.

How do they operate work:


Light Emitting Diodes (LEDs)
Instead of using a filament (like incandescents) or gas (like CFLs), LEDs produce light through the flow of electrons in a semiconductor material made of positively and negatively charged parts. When an electric charge strikes the semiconductor (i.e. the light is turned on), electrons flow through “holes” in the material from a negative to a positive layer. As the excited electrons pass through the positively charged holes, they create light which causes the LED to illuminate.
Induction Lamps
Induction lamps are somewhat similar to fluorescent bulbs in that they create light by using an electromagnetic field to excite mercury particles mixed in an inert gas. However, instead of using metal prongs, which often break or become stripped, induction bulbs are excited through a powerful electromagnet positioned outside the bulb. This setup also eliminates the problem of leaky bulbs (common with fluorescents), where outside gasses seep inside and disrupt the balance of inert gasses.

LED lamps, the more expensive alternative gets most of the buzz, but induction lamps are more superior

From SEGA technologies

 

LED lamps get the more attention but are more expensive.  The real winners in terms of longevity, lumens per watts are induction lamps

Induction lamps have lifespan of over 60,000 hours and has 50% less energy consumption compared to CFL, mercury vapor, high pressure sodium lamps

LED have light conversion efficiency of 55 lumens per watt;  there are those with 70 lumens per watt but are expensive.  Induction lamps have efficiency of 65 to 82 lumens/per watt.  Thus a 200 watt LED will produce l1,000 lumens (the claim for 12,000 lumens for a a 120 watts fixture was over stated?) and a comparable induction lamp will produce 16,000 lumens (on the high side).  Thus induction lamps would have superior in high illumantion area like theater, gyms or outdoors (we should have read this before)

They have faster restart, high power factor, and uses less mercury (and therefore less toxic) and more environmentally friendly

Price:   induction lamps will cost 75 to 80% lower than a similar LED lamps fixture.

Advantages of Induction lamps

1.  Longer life since there are no electrodes that degrade;

2.  Lower operating cost

3. High power factor

4.  Instant restart compared to MV and HPS lamps;  there is not much heat generated;

5.  Lower maintenance cost due to high lumens/watts;

6.  Use less mercury vs flourescent and CFL lamps

• These benefits offer a considerable cost savings of around 50% in energy and maintenance costs for induction lamps compared to other types of lamps that they replace.

Which is more superior: LED lighting or Induction lighting

                                     

Our companies bought over half a million worth of LED lamps last week. Last night, I saw most of them and they were good.  This morning I read posts on which is better:  LED or induction lighting.  I think we jumped too soon on the LED, although function wise, we were right because the use was for street lighting

Thus induction lamps are less expesive and has higher lumens output over comparable power consumption.
                                          





Thus we can see that induction lamps has longer life than LED and other similar lighting system

Welcome to Energy Efficient Lighting site

                              

Green innovation, social entrepreneurship is about planet, profit and people and how to balance the 3.

Planet involves green technology and green innovation and energy use.  There is not much fossil fuel left, and not much energy source left to power cars, light up cities at night, heat cities in cold areas, or cool the offices during hot weather during the day.

We really have to think of innovative ways to save on fossil fuels:   fossil fuels emit carbon which cause/lead to global warming.  Fossil fuels source is also limited.  Coal was formed from decaying vegetable matter millions of years ago.  But we strip coal mining site and consume them at prodigous rate, and emit carbon at same rate.  Yet many of power plants that are running are, on base loads are fed with coal.   To avoid this, we have to lessen electrical energy consumption.  And the most numerous appliances come from lighting.

Many power plants too are fed with diesel and bunker fuel.  Oil based fuel are also decreasing in amount and the increase in prices reflect the level of supply vis a vis the demand. Petroleum, formed million of years ago from decaying animal matter.  Do we have the luxury of million of years to replace our petroleum supply?

 Shell in its future lens scenario, does not see gas any more as the leading power source of transportation in the next several decades.  And solar, will be in the next 50 years, the top source of electrical energy

There are various new technology that produce brighter lamps, but consume less electrical energy:  LED lamps and induction lighting.  We shall explore them soon.
