There are a lot of different ideas in the lighting industry about what good advice is and what is bad. Here is a quick overview of some of the worst lighting advice we’ve ever heard and why.
Light levels don’t matter
Light levels are important to any lighting project. If you can’t see what you need to, then the light is useless. Light levels need to be taken into consideration. If it is a sign people need to be able to read it. If it in a parking lot safety and security is the primary concern. Light levels vary from project to project and must be task specific. You don’t want you back yard lit up like the middle of the afternoon, but you also don’t want a parking lot so dimly lit that if you drop your keys at night you can’t find them.
Color doesn’t matter
Have you ever looked at those yellow lights that you see along the highway? Compared to crisper white light, they are strenuous on your eyes. You are used to seeing things in the daylight, and sunlight is about 5900-7500 Kelvin. Granted at night you don’t need the sun shining down on you to see, but you want to see as close to natural light as possible for your eyes to recognize things. With the amber colored low pressure sodium lamps you can hardly tell the color of a car, but with whiter light produced by LEDs, you can easily recognize colors, shapes and details much easier. Granted, in environmental conditions, like coastal areas, low pressure sodium or amber light is necessary to reduce the impact on wildlife.
The higher the wattage, the better the light
Every application needs different lighting levels, but a higher wattage light does not always produce better light. LEDs provide amazing light at much lower wattages than any other type of lamp. You also don’t want a huge bright spot light on a small sign or a huge high powered flood light for a roadway that potentially blinds travelers. Instead, using the right wattage light to provide the task specific lighting will save money as there will be no wasted energy. It will also be easier on your eyes.
You need full intensity light all night long
Security purposes require full intensity lighting to happen all night; however, a lot of applications allow for a dimming option. Between certain hours of the night, wasting the energy on full intensity lighting when no one is there is just that, a waste. Instead, if the area still requires lighting, dimming the fixtures down, which is now possible with LEDs, can save money while still providing some light. There can even be motion activators in the area to bring the lights back to full intensity when there are people in the area. Having the lights suddenly spike back to full intensity would also alert anyone nearby that there is someone in the area triggering the lights.So there you have it. What advice have you ever questioned that you have gotten about lighting?
