LEDs Versus Metal Halides
Currently metal halides are more popular in the rental market, mostly based on price. However, while metal halides certainly have a place on the jobsite, it is important to consider more than the up-front cost. Metal halides are ideal for companies infrequently working night jobs or shorter duration projects where contractors can rent a fleet of them on the cheap.
The eruption of LED technologies means a huge leap when it comes to fuel economy, durability and safety in light applications. The higher the running hours, the more appropriate LED lights are.
Fuel: When looking at fuel savings, metal halides are fuel-efficient units, but nowhere near the cost savings of LEDs. Some models are so efficient when compared to traditional towers that the user may save up to one dollar per running hour. Multiplying the total running hours by the total number of units on a project can equate to large savings.
Maintenance: LEDs hold a distinct advantage in this category. LED components last much longer. Additionally, the light can be switched on and off similarly to the lights in a house, immediately providing full luminosity. This is vastly different than metal halides, which take time to turn on and provide the ample cool down time the machine needs before shutting off. In the event the unit becomes too hot, it could take over 20 minutes to recover full brightness again. Because of this, it is much simpler and quicker to reposition an LED.
Lighting: Illumination is improved with LEDs for multiple reasons. For one, LED light is a brighter, cleaner light — similar to daylight. LED light also travels farther than traditional light. When it comes to staying power, there is nothing better than LED. Its traditional counterparts run hotter, leading to more frequent burnouts. True, LED bulbs are more expensive to replace than traditional bulbs, but they last much longer. Light bulbs are not overly costly to replenish, but over time all the replacements add up and can equate to lost time on a jobsite.
