The online retailers at Simple Lighting have explored the views of lighting specialists who have questioned the validity of a recent study into the impact of light emitting diodes on our retinas.

However, now experts in the field have spoken out about the concerns over the study, which they believe “fails to stimulate realistic conditions for the retinal cells.”

It has been reported in Lighting.co.uk that researchers at the University of Madrid made the claim that blue light emitted from LEDs causes damage to human retina cells, following an experiment that exposed In Vitro retinal pigment epithelium cells from healthy human donors to light from blue, green, white and red LEDs. The study was subsequently taken out of context with some media sources quoting LEDs as causing blindness.

However, now experts in the field have spoken out about the concerns over the study, which they believe “fails to stimulate realistic conditions for the retinal cells.” In particular, Steve Poole, technical/quality director at Projection Lighting and former manager at the Lighting Association Laboratories shares his beliefs that the experiment was flawed, stating that “the report describes the exposure levels that the retinal cells were subjected to, but they aren’t really relevant.” He goes on to explain that the conditions endured throughout the research equated to staring at blue light “equivalent to a 100W incandescent source” from just 20cm away for 12 hours, are not a realistic level of exposure.

Further to this, others have argued that more research into how the “eye mitigates blue light hazard through pupil dilation” should be made a priority.

As one of the country’s favourite suppliers of domestic and commercial LED lighting solutions, including LED tape lights and strip lights, the team at Simple Lighting are often approached by those interested in the benefits of the solid state lighting. As well as being more energy efficient, the lights help homeowners to save money and regular research is continually identifying new areas of use all the time. Naturally the initial news was of concern to the team and a representative has shared their thoughts on the new opinions.

“From what we’ve read from experts in the field, it seems as though the study was not thorough enough and there were perhaps flaws in the set up. It will be interesting to see whether any further research in this area will now be undertaken and the results that this shows.”

Established in 2009, Simple Lighting Company aims to provide high quality lighting at some of the most competitive prices on the web. The company has grown considerably in recent years and supplies over 4000 products, specialising in LED lighting, LED tape lights, LED strip lights as well as indoor and outdoor lighting.
