subject: Kind Of Emergency Lights That You Should Avoid Purchasing [print this page] There are a lot of manufacturers offering a wide variety of emergency lighting equipment to be used in critical situations. The fact that you need to use these lights in critical situations means that you have to choose well and choose wisely. A list of features that you would expect from your emergency lights can help you guide through the process of picking up a lights bar for your emergency vehicle. However, there are also certain red flags that you should look for in equipment and when you find them it is a good idea to not invest your money in them. Given the reliability and resilience you expect from emergency lighting equipment it is better not to compromise on the performance of the emergency lighting equipment.
You must never purchase lights for emergency vehicles without double checking if these lights are adherent to the standards set by SAE or California Title XIII. It would be risky to pick any equipment for emergency situations if they are not certified to adhere to these standards. That is why most professional manufacturers of emergency lighting equipment make sure they follow all the guidelines as far as emergency lights are concerned. Whether it is a lights bar or a dash and deck lighting equipment, it is imperative that they are reliable, a factor that can be proved only if they are certified as per conventional standards.
You should also avoid purchasing emergency lights for vehicles based on their cost and rather look at the performance that they offer. For example, the presence of parabolic reflectors, wide angle, UV resistant Lexan domes and optic spreader filters could greatly enhance the quality of the lighting. Clear replaceable polycarbonate inner and outer lenses too are used to collect and spread the beams emitted from LEDs. In some cases, diamond mirrors are used as well to increase the visibility of the lighting. Normal light heads wouldn't be as effective as an advanced emergency lights bar which can offer a wider coverage and a greater penetration of the warning beam without scattering. It is important to check what kind of optical elements are introduced in the design and how they perform when required.
Emergency lights that don't use LED modules are best ignored for the simple reason that LEDs provide long operational life in excess of 50,000 hours and consume very less energy. 4 Watt LEDs are used in a modern lights bar in LED modules that can flash very brightly. The LEDs don't give out a lot of heat even after prolonged usage. Besides, they can be operated for long hours and made to flash at very high rates. Two significant factors that tilt the scales in the favor of LEDs are that their lighting intensity can be controlled easily and that they can be made to emit lights in different colors across the spectrum. These factors put together make LEDs a far more reliable, efficient and effective option than other contemporary lighting options available to us.
