first liquid cooled LED light bulb

The two major problems with LED lights are they are very directional light source and the LED chips can get hot when operating for a long time which can potentially shorten lifetime if the LED bulb is not cooled properly. Eternaleds introduced the first liquid cooled LED bulb called the HydraLux-4 which uses a fluid inside the LED bulb to not only cool the bulb but disperse the light 360 degrees around the bulb. The 4 watt bulb is equivalent 24 watt incandescent bulb and is offered in two colors, Warm White and Daylight White. By the end of this year the company is expected to release a 8 watt, 12 watt and 16 watt versions for people who want more light output. The HydraLux-4 only cosst $1.75 per year to operate and over the lifetime of the bulb can save up to $157 in electric and replacement costs compared to an incandescent. what do you think about the Eternaled...

ascent solar makes efficiency progress

The National Renewable Energy Laboratory (NREL) recently verified that Ascent Solar‘s flexible Copper, Indium, Gallium, Selenide (CIGS) solar panels have an efficiency as high as 10.4% This is great news for flexible solar panels since they continue to get better in terms of how much sunlight they can turn into power. The flexible solar panel that was tested by NREL came right off a Ascent Solar’s production line which puts confidence in Ascent Solar’s ability to manufacturer 10% efficient flexible solar panels on a commercial level. The solar cells are produced on durable, light weight plastic, the plastic substrate materials result in higher power levels, compactness and flexibility that enable the solar cells to be configured into a wide variety of rolls, foldable packs, or traditional solar panel...

LEDs vs. Incandescents, round one.

We were at the ecotuesday event in Santa Monica this week and people mentioned their curiosity about LED lighting. One member at the event even said he replaced a bulb in his home with an LED light bulb and said he loves it but also mentioned it “costs too much.” Is that really true? Do LED bulbs really cost more than Incandescents, well let’s find out. Below is a table we put together that shows a head to head comparison between a LED and Incandescent bulbs. LED Incandescent Lifespan 50,000 hours 1,200 Hours watts used 7 60 kWh consumed per year 20 175 costs per kWh $0.10 $0.10 total annual operating costs $2.00 $17.50 cost for bulb $49.99 $1.50 replacement costs over 10 years $0.00 $36.50 total investment over 10 years $69.99 $213.00 Comparing the LED with an Incandescent bulb over a 10 year period, it’s quite easy to see that LED bulbs are the more cost effecitve method to go with. Would you agree with our calculations? Do you think LED bulbs a good investment for the...

Seattle buys into LED street lighting

Seattle announced that they would be switching to LED streetlights by investing 6 million dollar of federal stimulus money into replacing 40,000 HPS (high pressure sodium) streetlights to high effiencey LEDs. It’s estimated that the transition to LED streetlights will take between 4 to 6 years. The mayor of Seattle, understands that LED streetlights don’t get as hot as HPS light bulbs. Heat is a key indicator of energy loss. LED streetlights not only save the city on energy costs but also last up to 10 years longer than standard HPS streetlights which reduces annual maintenance costs. If more cities across the US invest in LED streetlights not only would it generate millions of negawatts (negative watts) but it would make LED lights more affordable since the manufacturing volume would increase. What do you think about LED Streetlights? Is your city considering replacing old HPS lamps to LED...

Sharp’s seven shade LED light bulb

Can’t decide between a Cool White or Warm White LED light Bulb? Sharp’s unique LED light bulbs can be adjusted 7 shades so you can have the type of light that fits your mood without having to change the bulb. A remote control that lets you cycle through the different shades of light is included with the Sharp LED Light bulbs A series of Sharp’s LED Light bulbs can be connected to a single circuit and can be all adjusted with a single remote control. The great aspect about LED are they have an efficient lumen to watt ratio and feature an extremely long lifetime. The energy savings combined with savings gained from fewer replacement costs make the return on investment on LED bulbs very attractive for places with high electric rates. Sharp’s adjustable LED light bulb will be released in Japan next month, it’s unknown today when the unique LED bulb will be released to other markets. What do you think about LED light bulbs that allow you to adjust to temperature of the...
