The 5 critical steps to a successful LED Light project!
When contracting an LED Light provider you need to ask 5 critical questions:
1) What Energy efficiency is provided?
Energy efficiency is measured in Lumen output/Watt (Lm/W). Many cheaper products feature low energy efficiency of 80-100lm/w, but you can double your energy savings (or lux levels) by choosing LED Light products with an energy efficiency of 150-160lm/w.
2) What Lux levels are provided?
The end result in your site will be the light levels (lux levels) and the starting point will usually be around 150lux. With LED Lights you can really push the lux levels higher and reach the recommended levels of 250-300lux for warehousing and 500lux for offices. This result is reached as a combination of how many fittings you install, the position of each fitting and the lumen output of each fitting. These numbers can be calculated in a Dialux model before the project is signed off.
3) What color LED chips will be provided?
LED Chips have different colors. From 2500 Kelvin (yellow) used in many coffee shops to create an atmosphere of 6500 Kelvin (blue) used in bathrooms and other very clean rooms. A low kelvin creates a cozy atmosphere but makes it hard to read and concentrate. A high kelvin will make it easy to spot dirt in clean areas but will lower productivity by interrupting sleeping patterns and affecting the general health of the workers.
4) What driver brand is provided? The LED Driver determines the lifespan of the LED Fitting and low-cost products often will feature a low-quality driver which will only last 2 years time. Most respected Industrial LED providers will provide High Spec drivers and have them tested before installation. This will ensure the LED fitting lasting 5-10 years if not longer.
5) What sensors & automation are provided?
Sensors can reduce energy consumption significantly and it the same time prolong the lifespan of the LED fittings by up to two years. The most used types are as follows:
– Motion sensors, which will dim the lights when there are no people around.
– Daylight sensors, which will dim the lights when the sun shines through the skylights.
– Some companies opt for full LED Light automation with a central unit controlling light levels.
