Answers to Common Questions about Commercial Lighting
- Answers to Common Questions about Commercial Lighting
What Types of Commercial Lighting Are Currently Available?
A lot of buildings still have older types of commercial lighting such as incandescent bulbs, HID or high intensity discharge lighting, or T12 fluorescent lighting. Newer types of commercial lighting include T8 and T5 fluorescent lighting and also LED or light emitting diode lighting.
Does Commercial Lighting Generate A Lot of Heat?
Older lighting such as incandescent bulbs and halogen lamps do give off a lot of heat which is why they are so inefficient and waste so much electricity. The way those types of lamps work is that electricity runs through a thin wire called a filament, heating the filament to the point where it glows and gives off light. Unfortunately, a very small percentage of the electricity used is given off as light and most is lost as heat.
Fluorescent lighting and LEDs produce considerably less heat to the point where heat is really a nonissue.
How Does an LED Work?
LEDs stands for light emitting diode. A diode is a semi conductor that allows current to flow in only one direction. One side of the diode has a surplus of positive electrons and the other side has a surplus of negative electrons. When voltage is applied electrons begin to flow and when they pass through the positive/negative junction they give off light. It’s really a lot more complicated than that but that is the simplified version.
Why Are LEDs so Expensive?
There are a number of reasons why LEDs are so expensive. One reason is that a lot of money went into research and development and the companies that came up with the technology are still trying to recoup their investment. Another reason is that there aren’t as many LEDs being manufactured as there are other types of lighting and simple supply and demand makes the price higher. LEDs do last for a very long time and are incredibly energy-efficient so it may still be worth the upfront investment because they will pay for themselves eventually.
Does Upgrading to a Newer Lighting System Really Result in Significant Savings?
The answer to that question is a resounding yes. If you are replacing T12 lighting with newer, T8 lights you could save as much as 50% on your energy bills. T8 lamps are far more efficient than the older style of lamps and they are also brighter so you will not need as many of them to produce the same amount of light.
