Where $60 MILLION dollars in LED Research is going…
So where does $60 million in LED research going? It seems a large chunk of grants from the department of Energy is going towards improving the 3 things that we’ve been talking about for a while: Price, light output and color.
- Price - Bringing down manufacturing costs and ultimate end costs to the consumer by improving the materials used and finding cheaper alternatives to creating LEDs.
- Light Output - Focusing on creating LED dies that are brighter, lenses that don’t cut light output and cover the LED “dots” that people see in bulbs and fixture, as well as creating fixtures that can be used by consumers that are bright enough to replace a 100W incandescent bulb.
- Improving the color output - Researching new phosphor materials (which are currently being used in fluorescent lighting as well) that make LED light “warmer”
Looks like CREE, Philips and GE are receiving the bulk of grant money. It will be interesting to see what they can come up with as well as what the future brings for LED lighting… My question is how long until all this great research is APPLICABLE to us? 2,3,4 years? Let’s hope not…

The Rise of Residential LED Lighting and What You Should Know
Almost everyone today knows what an LED light is in the most general sense, but few are aware of how fast it is set to become the main source of general lighting in both homes and businesses. Everyone from the Department of Energy to environmental advocates are pushing the pace of LED general lighting development because of the dramatic savings in energy associated with their use, and the fact that LEDs use no environmentally harmful substances like some older energy-saving bulbs (i.e. compact fluorescents which contain mercury).
Although light emitting diodes have been around since the 1960’s, their use up until several years ago was confined to such things as indicator lights in electronic devices, traffic signals and instrument panels. It wasn’t until the invention of the white LED (in the late 1990’s) that people began to take a closer look at their ability to replace incandescent lighting in homes or businesses. Being a technology that uses a semiconductor to produce light means that the output and efficiency of LED lights is improving at a rapid pace; today’s LED replacements can achieve a life span of 50,000 hours while consuming 80% less energy than a standard incandescent bulb. LEDs that produce a warm white light were invented by accident in 2005 but will allow a person to replace their incandescent bulbs with a similar color light to what they’re used to. An additional benefit of LED lighting is that only a very small amount of UV or IR radiation is emitted, making it highly useful for locations where valuable art is hung on the wall or fading may be an issue.
The current market is full of LED replacement bulbs and lighting solutions, but it is also buyer beware. There is a lot of junk on the market today that if bought and tried will surely disappoint you. Well made LED replacement bulbs are still pricey and the cheap products on the market today, a lot of them being sold through big box stores, will not last nor produce or sustain a bright enough light. On a side note, LED bulbs (LEDs don’t really need to be a bulb!) don’t usually “burn out,” instead their usable life is measured by a certain percentage decrease in brightness. The Department of Energy is using considerable resources to promote LED lighting (also called SSL, or Solid State Lighting) and just recently announced the Energy Star specifications for residential LED usage. That means in the near future you will have some assurance as a buyer that the product you are purchasing really will live up to your expectations.
In the meantime, it is important to buy your LED lighting from a trustworthy source with good customer service in case of any problems you might experience with this new technology. Companies that have established their credibility by working closely with, and traveling to, the factories making the LED lighting they carry are a good place to start your shopping. Look for the offer of a money-back guarantee if you are unsure of what you are buying and how it’s going to work. Now is the time to start using LED lighting, but be sure to shop wisely and you will save yourself both time and money in the long run.

ANYONE can sell LEDs!
I just got an email in our inbox today. We get spammed about 5x a day from different manufacturers in China trying to get us to sell THEIR LED products. This one was particularly funny since it DID get my attention, but not in a good way, with their attached logo of a chinese baby “catching a wave”. (I can’t make this stuff up people)
The emails generally consist of a Dear sir/madam – followed by extremely broken English, with an attached pricelist asking us to consider them to be our manufacturer.
Here’s an excerpt:
“Dear Sir,
This is Vickey who come from Shenzhen *** ,LTD .I am kindly know you are in the market of LED lights.I would like to indroduce our comapny and products to you ,Hope to we could build business relatioship in 2009.”
I left the spelling errors in there on purpose. Do they REALLY expect us to buy their products, if the first sentence in their email is plagued with grammatical and spelling errors?
There are literally hundreds of new manufacturers in China trying to jump on the LED bandwagon, and make LED light bulbs. The question is what % of them are complete garbage?. We’ve taken the time to contact a number of manufacturers and tested their products thoroughly, before deciding on who to go with which is why we can offer a 2 year warranty and 30 day guarantee.
Once again, buyer beware – there’s a ton of new websites cropping up selling LED lights, at LOW prices. Their manufacturer can very well be the one who can’t even hire someone who speaks english, or uses surfing chinese babies in their logo…would you spend $40-$100 with them?
Anyone else seen some questionable websites? We’ll be happy to scope them out and give you the lowdown.
