The new generation LED technology has come as a boon especially with the increasing energy costs. LED lights are replacing fluorescent lights, xenon flash lamps and filament light sources. The lightbar for example, is highly innovative and solves several purposes. Firstly of all, several 1 – 10W LEDs are assembled together to create the light bar. Since it is only an assembly you can go on increasing the intensity of light depending upon the requirement without increasing the cost to a great extent. The circuit is extremely simple as well and hence instead of 2 rows with a dozen LEDs you can have 4 rows without a great change in the circuit. This isn’t really possible in other light sources.

A great advantage of the lightbar which isn’t seen in any other light source is the fact that you can control the LEDs assembled together, which means you can conserve energy when there isn’t any need for bright lights. Moreover, the fact that there are several rows of LEDs, with independent control of each row, adds versatility to the configuration. You can have multicolored LEDs put together and flash them alternatively ...
... giving a brilliant and colorful effect. All you need is a simple push button, cigarette lighter switch and a simple circuit.

A lightbar can be designed from simple light emitting diodes, each of which can carry on and on, in excess of 50,000 hours. So, you would hardly ever be deceived by a light bar during an emergency. This reliability is seldom offered by other sources of artificial light, another reason for the popularity of LEDs, whether it is for emergency lighting or it is for decorative purposes. For example, you can have a light bar casting a beautiful soft blue aura from behind a display cabinet lending beauty to your living room. You can leave it on for hours without worrying about energy costs.

LED lighting is very useful not just for emergencies but also for domestic uses. LED lighting can work on flexible voltage which is a great answer for houses troubled by power fluctuation. Unlike fluorescent lights, a lightbar will start immediately. Moreover, you can be assured that the lighting is clean and that your decoration isn’t really costing the planet much compared to other light sources which use up a lot of current and also waste a lot of energy through high heat dissipation. The LED light bar is known for intense beams with low beam temperature, which is another reason why it is used. Other light sources can be very hot, causing people to sweat and fume in closed party halls or discotheques.

The flicker free lighting that is offered by a lightbar is something rarely seen in other light sources even under voltage fluctuation. You can control the intensity and dim the lights if required. The resilient shatter-proof design of the LEDs gives them greater life. Unlike most other light sources, LED light bars don’t break or stop functioning when dropped accidentally.
