TORRANCE, CA --   Energy-efficient T8/bi-pin LED lighting tubes are the latest fluorescent-replacement LED lighting products LEDtronics announces adds to its green-technology lineup.

LEDtronics
® series LED48T8-288-001W bi-pin LED fits into standard G13 bases and is designed to directly replace conventional T8 fluorescent tubes that provide general lighting for commercial, residential and architectural lighting applications. The 48" long white tubes provide the equivalent light output of 24 to 32-watt fluorescent lamps while consuming less than a maximum of 19 watts. In addition, the LED48T8 tubes run on a wide voltage range of 100 to 290 volts AC.

When it comes to rated life, the LEDtronics series LED48T8 really shines.

50,000 hours and more!

While conventional fluorescent lamps typically have a rated life in the range 8,000 to 24,000 hours, the LED48T8 lamps boast an operating life of 50,000 hours and more -- 5.7 years of continuous light. Furthermore, since the LED lights produce so little wasted heat, the temperature inside the fixture does not build up as it does with conventional fluorescent tubes.

The sturdy construction of a UV-resistant polycarbonate housing over the LED tube provides increased protection (no glass to break) and shielding against many environmental effects, allowing them to be placed in locations where typical lights would be more vulnerable to the elements. 

Hot and Cold Temperature Applications

LEDs perform well in temperatures from -35C° to +45C°, making them ideal for applications subject to frequent on-off cycling, such as garages and basements, while the aluminum back cover helps with better heat dissipation and a longer lifetime for the LEDs.

The LEDtronics LED48T8 lights deliver up to 1,342 lumens at a color temperature of 5000K (pure daylight white) and 1,072 lumens at a color temperature of 3000K (warm white), compared to the average 810 lumens for equivalent conventional fluorescent tubes. They provide a brightness of up to 429 maximum foot candela across a 114-degree beam pattern, with an impressive CRI of 80.

Other benefits of LEDs over fluorescents include: Quick and easy installation to minimize retrofit costs; no ballast and starter needed, thus no radio frequency to interfere with radio and television signals; instant, full-strength lightup; no buzzing or flickering; and directional distribution of light--good for interior task lighting.

Solid-state design renders LEDs impervious to shock, vibration, frequent switching and environmental extremes. Savings from reduced maintenance costs and downtime quickly return the capital investment expenditure, making them as friendly to the environment as they are to the operating budget. The positive environmental impacts of LED lights additionally come from the consistent, reduced power consumption, long service life, high-quality light, and cold temperature operation, with the corresponding reduction in greenhouse gases and the reduced waste from fewer replacements. Unlike conventional fluorescent bulbs, LED lights are not disposed of as hazardous waste at end of life.

The LEDtronics LED48T8 tubes comply with RoHS--the lead-free and mercury-free directive, as well as the CE safety assurance. They emit no infrared or ultraviolet radiation, and effectively reduce light pollution, being compatible with the international "dark skies" initiative.

The LED48T8-288-001W Premium 4-ft (1200mm) Tube Lights come in two colors: Warm White (SIW) and Pure Daylight White (TPW). Other viewing angles, tube lengths and a variety of LED colors are available for OEM customers. Large-quantity discounts are available for qualified distributors. Availability is stock to 6 weeks.

Bridgelux LED Arrays Break Costs With Efficiencies

An LED light, as packaged by Bridgelux



Bill Watkins had a lot of career choices to consider after his surprise departure a year ago as chief executive of Seagate Technology. Now he's found his new focus-illumination. The veteran disk drive executive is the new chief executive of Bridgelux, a well-funded startup that is entering the market for solid-state lighting devices.

"Metal halides are the highest-quality light source. Conventional LEDs cannot put enough light in a small space to replace them," said Bridgelux president Mark Swoboda. "These light sources have every bit of the oomph to create enough light. They can pretty much duplicate what the high intensity discharge lights can do."

The ES and LS series, meanwhile, are geared toward replacing conventional compact fluorescents and incandescents. Bridgelux does not make complete bulbs or lamps. Instead, it provides the LEDs and all the electronics in an integrated package that others can assemble into a final product. Expect announcements in a few months that will try to increase the interoperability of LED components with the existing lighting industry.

"The light market is used to a socket and a bulb," said Swoboda.

Although it has been promised for years, the solid state lighting revolution finally appears to be close at hand. For one thing, policy will dictate it: incandescents are already being phased out in Australia and the EU; Canada, the U.S. and others will follow with similar regulations that take effect from now through 2014.

Bridgelux, now based in Sunnyvale, Calif., has raised about $70 million already and is just announcing another funding round of $50 million, led by VantagePoint Venture Partners. The company plans to set up a new factory for making LEDs in Livermore, to the east of Silicon Valley.

Technology plays a role, too. High-end LED lamps have dropped 30 to 60 percent in price from a year ago, Swoboda said. The lower price, combined with the fact that LEDs require far less maintenance and energy, are making the economic argument attractive. Ideally, LED bulbs will cost around $25 in one to two years. (Today, a 60-watt equivalent can cost $40 or more.) Because the lights save around $15 in yearly electricity costs, demand is expected to escalate. The video here shows one of the first Bridgelux arrays.

Mark van den Berg, a VantagePoint managing director, estimates that LEDs are roughly ten times more energy-efficient than incandescent bulbs. They are also, unfortunately, much more expensive. Van den Berg says a consumer can buy an ordinary bulb for as little as two for fifty cents, where a decent fluorescent bulb for home use is $12.99 or so (low-quality versions are quite a bit cheaper, he allows), and an LED light is now $30.

"But it's on its way to ten bucks" within 12 months, he says, with companies like Bridgelux helping to improve the technology.

Who will make it in LEDs?

It's hard to say at this point.   The company's light arrays do cut the price of LEDs, and in general, Bridgelux is fairly well regarded. Other start-ups to watch include Luminus Devices (large, bright LEDs), Lunera (sideways LEDs) Renaissance Lighting (fancy fixtures) and D.Light Design. Entrenched players such as Philips Electronics, Cree, Toyoda Gosei, Osram (known as Sylvania in the U.S.), and Nichia. 

The challenge will come from multinationals  -- General Electric, Philips, Osram, TSMC, Toshiba, Panasonic, Sharp, etc. -- who also want to dominate the market. Expect  acquisitions and consolidation within a few years.

But LEDs aren't the only light technology coming to market.

Luxim announced it has created a street light around its plasma light bulb that it says can save $145 per fixture. Luxim's bulb is about the size of a Tic Tac, but it emanates about the same amount of light as a spotlight. The light is generated by intensely focusing energy on a small chamber of gases. Luxim originally marketed the bulb to the projection TV industry, but that effort eventually died out.
