LED Lighting Myths Dispelled

LED light from digital lumensThis article is sponsored by Digital Lumens.

In the last five years, LED lighting and controls have been widely used in a broad range of general lighting applications, from residential to commercial, but there are a number of persistent misconceptions about LED lighting – many based on knowledge of legacy fixtures – that do not apply. In fact, for commercial and industrial applications, high-quality LED fixtures offer extremely low energy use, a long lifespan, high-quality light and durability. Additionally, there is none of the maintenance (re-lamping, re-ballasting) associated with traditional incandescent and fluorescent sources and there are inherent controllability aspects (instant on/off, full-range dimming) that create additional energy savings opportunities.

LED lighting is relatively new compared to legacy lighting types, and continue to be misunderstood in a number of ways, writes Digital Lumens in a new white paper devoted to correcting these misunderstandings. One common misconception is that LEDs are so efficient that controls are unnecessary. In fact, while switching to LEDs creates a one-time savings event – typically reducing lighting energy use by up to 50% – integrated sensing and controls can nearly double those energy savings, making controls essential for maximum savings and project economics.


Another misconception is that LED lighting prices will go down so it pays to wait. The truth, says Digital Lumens, is that the major LED chip price drops have already happened; the rest will be incremental. And the energy savings from upgrading to LEDs far exceed any modest price declines in LED-based fixtures. So waiting for a price drop will cost more in energy savings than savings from LED price declines.

There is also a misunderstanding about the environment in which LEDs work, Digital Lumens says. While many believe that LEDs don’t work well in high-temperature environments, the fact is that in temperature tests conducted by independent labs, LEDs performed equally as well as fluorescents and HID fixtures. Of course, the company adds, quality matters, and a well-designed lighting system that carefully manages heat dissipation is a prerequisite for lighting operating at any temperature — hot, cold, or anywhere in between.

Interest in LED lighting is at an all-time high as energy efficiency and corporate sustainability initiatives are increasingly important worldwide. But because LEDs are fundamentally different from other lighting types, it is critical to understand the characteristics, benefits, and opportunities they present, and working with a partner who understands the best and economical lighting design for any particular building and organizational needs can make an enormous difference, according to Digital Lumens.

  1. Appearance:New energy saving bulbs provide the same yellow light as the old-fashioned bulbs and they don’t flicker.

    Fittings: Energy savers come in bayonet and screw fitting, just like the old bulbs.

    Start-up:Halogen and LED (light emitting diode) lights come on immediately as soon as switched on and new “quick start” compact fluorescent lamp (CFL) bulbs come on in less than 30 seconds.

    Flexibility:Halogen bulbs are best for using with dimmer switches.Both halogen and LED bulbs can be used with timers or movement sensors and these are also best for use in cold areas such as pantries and garages.

    Cost:Although new bulbs seem expensive, they save money in the long run.Some can last for 10 years or more and they cut electricity bills.One £5 CFL bulb, for example, should pay for itself in just one year, says the guide, saving up to 80% of energy compared to a traditional bulb.

  2. LEDs are also such a different technology that they’re being combined with other tech like controls, speakers, and a future improvement to WiFi (called LiFi).

  3. Nice article Jennifer. And just to add to that, In India, government has created innovative program to promote LEDs for lighting to spread the initial high costs where they can buy upfront at a fraction of the cost and pay for through their regular electricity bills, allowing people to spread the initial installation costs.

  4. The scheme is available to both domestic and non-domestic customers. Against market price of Rs 350 per LED bulb, the same is being made available at about Rs 100 per bulb. Consumer will pay Rs 10 per bulb at the initial stage and Rs 10 per bulb per month will be recovered through subsequent electricity bills. Consumer can also save up to Rs 15 on three LED bulbs by adopting the upfront payment mode.
