5 LED Myths to Dispel

Among modern sustainable lighting devices, the interest in LED lights has been rising for both home and industrial lighting. However, though benefits on energy savings are pretty evident, a lot of misconceptions about this technology still circulate.

So, here there are a series of LED myths to dispel.

1) « LEDs are too exprensive »

It’s a big mistake to estimate LED costs by comparing them to incandescent or fluorescent lighting, because that means restricting your propects. Since LEDs consume less energy, you can save up 70% a year and it means that you will be able to get back the starting investments.
Moreover, LEDs makes you less prone to strong (and unpredictable) rises of energy costs and still maintain a good savings on the bills. Plus, mantainaince is unnecessary and so you will benefit from a long-term saving.

2) « LEDs aren’t very bright »

This myth circulates since the first LED appareance, when they had a limited range of output and they often were not very bright and could prove to be less effective in spaces that needed nore light. Nowadays the lumen power is so vast that you can choose the appropriate intesity for each use.  The light efficiency, in fact, should be calculate based on lumen (lm) and not on electric power (W).

3) « It’s not worth investing in control options »

The long duration of LED could lead many people in believing that it could be sufficient in order to get the highest energy saving. Actually installing different kind of control and automated management devices on LED systems could optimise the whole lighting.

4) « The environmental benefits of LEDs aren’t worth the expense»

It’s unusual for a facility to make a decision to upgrade to LEDs purely based on environmental impact. Even when there is full awareness of the sustainability benefits, an upgrade still has to be cost-effective. With an LED upgrade, the reduction in CO2 emissions is only part of the benefit. The rest comes from the energy savings which add up to a significant return on investment.

5) « All LEDs are basically the same »

LED technology has evolved rapidly over the last five years, leaving facilities managers hard-pressed to keep up with all the latest changes in the market. It’s often assumed that there is no difference between LED products and therefore it’s not worth investing more than you absolutely have to. However, many poor-quality LEDs have a Colour Rendering Index (CRI) of less than 80 which will only make certain colours look natural and not distorted. In spaces where people will be working for long periods of time, you need to opt for LEDs with a CRI of 85 – which is the minimum legal requirement – and colour temperature levels of 3500-4000 Kelvin.
