LED Lights – Bad for your health?

Are LED lights bad for your health?

We’ve long been a fan of things that “work.” And one of those things are LED lights, LED lamps, LED bulbs, etc.


Because they were insanely energy-efficient, and a good long-term investment (both time changing bulbs, and money overall). What’s wrong with accomplishing a goal with less economic impact?


LED Lights are apparently “bad for your health”

Not going to get into details – but over the past few weeks or so, a flurry of “reports” came out saying LED lights are technically bad for your overall health.

Primarily because of the over-emphasis of the blue-light spectrum.

In general, those saying LED lights are “bad,” suggest that the blue light is disruptive to your circadian rhythm, and can cause other ill-health effects. Perform an internet search if you want to know more.

LED Lights bad for your health


Cui Bono? Who would want a “scare” with LED lights?

That’s the first question I ask whenever I see an attempted “paradigm change” in public consensus.

One might think that perhaps the POWER COMPANIES might want customers to switch to thirstier lighting instruments?

Or perhaps those that sell “traditional” lighting?

My money is on the power companies.

But what if you believe the LED light (blue light) theory?

Well – they sell glasses, which are not a bad idea to buy.

For one, most of you are staring at computer monitors – and worse – your smart phones all day long (Pokemon GO anyone?)

Those displays also emit a disproportionate amount of BLUE light – and can disrupt your sleep (for real).

You should invest (cheaply) in some orange tinted glasses. They filter the blue light – and still allow you to waste your time efficiently.

Here are a few options you can choose from. And they absolutely lessen the strain on your eyes. I’m in love with them now – even when not using electronic devices.

Sorta OT but I admit disappointment in the LED promise.

They’re billed as really efficient and long lasting. My experience has been that LED bulb QC is terrible. What good is a promising new technology if the manufacturing is dominated by lowest bidder crap?

Anyone know of LED makers who can reliably produce a product that won’t break within a year?

I agree on Cree. One of their advantages is that Cree makes their own LEDs rather than buying them on the spot market. Quality control is wildly variable at the moment, and the same bulb brand can be using chips from dozens of suppliers.

As for blue vs. yellow color temperature, the jury is still out – way out – on that. My iPhone and iPad have preferences available that allow me to set the displays to skew towards yellow over night, I use it, but I haven’t experienced any change in my ability to sleep.
Incandescent lamps are normally yellow (2700ºk for your light nerds) mostly because of the limitations of incandescent technology early on. Candlelight bulbs (2200ºK) lasted longer but were perceived as too dim, daylight bulbs (5000ºK and up) successfully imitated sunlight, but burned out too fast. 2700ºk becomes the “sucks less” compromise.

Once you have a consensus light source, everything else follows, so fabrics, wallpapers, paints, flooring – everything – is designed with looking good under 2700ºk lights as a prime parameter. It becomes the subjective normal.
