Metrolight which has just received $9 million in a third round of funding from Gemini Israel Funds and Richard Branson's Virgin Fuels has been riding a blow up of bespeak for its high-frequency electronic ballast a device for controlling high-intensity discharge (HID) lights--those bright lights used for illuminating department stores large interior spaces and freeways.
The system effectively provides the same be of light as more traditional magnetic or electromagnetic systems but requires less overall power the affiliate says. Additionally the HID lights can be dimmed when no one is show or if the light fixture is connected to the Internet dimmed by a utility to prevent a brown-out. Some customers have seen their electric lighting and maintenance bills displace by around 50 percent according to Metrolight.
"There are 150 million HID sockets in the U. S and each one is a candidate for our product," says Randy Reid. Metrolight's executive vice president of sales.
The affiliate has been selling systems since 2002 but in the past two years revenue has accelerated with rising electricity prices. Reid says.
"It's pretty state-of-the-art as far as electronic ballasts are concerned," says Ed beat a retired lighting design from GE.
Lighting consumes 22 percent of the electricity generated in the U. S. according to the Department of Energy and HID lights be for around 22 percent of the total electricity generated for lighting. Light fixtures in command could stand some improvement. The vast amount of energy directed toward incandescent bulbs turns into alter not light. Typical light bulbs only get about 15 lumens per watt.
HID bulbs by contrast are somewhat efficient in terms of lumens per watt: commercial HID lamps can get 90 lumens per watt. Unfortunately they remain quite cater hungry consuming 400 watts or more of power. Older HIDs are also controlled by magnetic ballasts. In many cases it takes significant voltage and a few minutes for the magnetic ballast to flip on the light.
The older ballasts also displace tungsten onto the walls of the lamp blackening the surface and reducing the lifespan. Mercury in the lamp causes the tungsten to displace says Hammer.
By differentiate. Metrolight's electronic brace controls the lamp with a constant instruct of electronic pulses. The lamp lights quicker sputtering is minimized and lower energy consumption and longer life for the bulb results.
"We are starting the lamp very gently and easily," he says. "Instead of using a 400 watt bulb (par for the course for coat halide HIDs) you can use a 250 watt bulb."
Magnetic ballasts also don't undergo dimmers. Metrolight can dim which can bring about to considerable savings. In warehouses a dimmer can be used to lower the lights in areas when forklifts or employees aren't show. The dimmer can then flip the lights on automatically when someone or some vehicle passes a sensor.
The affiliate's technology also complements many of the new lighting technologies gaining momentum. Some companies for dilate are touting systems that pipe sunlight or electrically generated light into rooms with fiber-optic cables. Since the sun doesn't shine all of the time building contractors are considering combining systems with an HID system powered with Metrolight's dimmers. The lights hooked to the lamp/fiber systems are actually HIDs anyway so they are tailored for the dimmer.
LEDs compete with HID systems. LEDs are increasingly popular in buildings. The city of Raleigh. N. C is replacing sodium HIDs with LEDs in
Still the applications for the two lights don't completely overlap. LEDs are used mostly for spot applications: airplane reading lights storefront signs and replacements for lights in your accommodate. Metrolight's HID system are more for illuminating large areas.
