Industrial Light towers are a crucial piece of building workplace equipment to hold an environment securely illuminated when employed at night or inside a dark interior. Although not all of the light towers are alike. Various solutions for light tower lamps are available, so contractors should be mindful of the variations in lighting systems to decide which equipment to use whether the light tower is ideally fit for a specific task or construction company. Although metal halide lamps dominated the market, the advent of LED lamps with its potential to cut fuel costs is beginning to gain ground, and the newly launched plasma bulbs provides a unique experience even though it’s still in its early stages. Here are three types of light towers that every contractor should know.
Metal halide lamps require much longer periods of time than other technologies to light up. Doug Dahlgren, marketing director for Allmand Bros Inc, says lamps with metal halides will take around five minutes to reach their maximum brilliance. The time increases when the lights are being restarted which is around 10 to 15 minutes, he says. Additionally, contractors will notice a change in the bulb life. Dahlgren points out that the metal halide device is made of a torch, ballast and condenser. He claims the bulb life expectancy usually goes down with higher wattages. Whereas a 1000 watt metal halide lamp usually has 10,000 hours of bulb life, a 1250 watt lamp generally has about 7,000 hours of bulb life. He also stated that the lamp achieves their maximum performance only if all of the components are built in a system.
Chad Hislop, associate product manager for Terex Aerial Work Platforms, says the main problem contractors will have is how big of an area do I need to illuminate? Is it just to light up the construction area or the nearby areas as well? If you need light to up the nearby area as well then another alternative may be better due to the steep light drop off with LED lamps. The other factor Hislop illustrates is that a client can make use of the savings in fuel. He stated that contractors require a situation of a long term usage in which they operate the LED light towers 24/7 to take advantage of the fuel savings. “You save the fuel by 40 per cent,” says Hislop. “When you are using light towers for a longer time period– especially when you’re using multiple light towers – the fuel costs tend to get very high, so that’s where you start thinking of options like LED.” A contractor who does not utilize the light towers so much, will take a longer time to realize the cost saving of fuel by using the LED light tower.
Plasma bulbs have been used by Multiquip in their H2LT light towers. The plasma bulbs provide 23,000 lumens which require only 255 Watts of power per bulb, according to Multiquip. There was also a Color Rendering Index of 94, says Bruce Coleman, Multiquip’s marketing manager. The plasma lamps are a fairly recent illumination system on the market for light towers. Bruce Coleman, product manager for Multiquip, says plasma bulbs are the highlight of the newer lighting technologies to complement the usage of hydrogen to produce electricity.
