What are the disadvantages of LEDs ? High up-front costs. Transformer compatibility. Potential color shift over lamp life. Performance standardization has not yet been streamlined. Overheating can cause reduced lamp life.
LED lights emit light from the short-wave, high-energy blue and violet end of the visible light spectrum. The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration.
The ‘blue light’ emitted by LED light bulbs has been linked to breast and prostate cancer , according to a new study. They are yet to research the effect of ‘blue light’ emitted by smartphone screens.
LEDs Use Less Energy Than Traditional Lighting Sources LEDs use between 25- and 80-percent less energy than incandescent lights . According to the DOE, the annual energy cost of a 60 W incandescent light is $4.80, but the comparable cost of a 12 W LED , providing the same light as a 60 W incandescent light, is $1.00.
Do LEDs save energy? LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light . LED bulbs use more than 75% less energy than incandescent lighting . Another advantage of LEDs is the “hassle factor.” LEDs last a lot longer than a regular bulb.
A 2012 Spanish study found that LED radiation can cause irreversible damage to the retina. A 2019 report from the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned of the “phototoxic effects” of blue light exposure, including an increased risk for age-related macular degeneration.
Scientists think nighttime exposure to blue light throws off your circadian rhythm, or sleep/wake cycle. This could lead to symptoms of depression .
Like a lot of peeps are saying in here, stay away from the shorter wavelength colors ( blue , indigo, violet). That being said, yellow and green , which are at the top of the visible spectrum bell curve, are easiest for our eyes to see and process.
This powerful color reduces emotional and mental stress and can help you fall asleep and rest easier. Try adjusting your LED light bulbs to a shade of purple after a stressful day while you relax and have a cup of tea.
Red light is less likely to shift circadian rhythm and suppress melatonin. Avoid looking at bright screens beginning two to three hours before bed.
Use Computer glasses or Anti-reflective lenses Computer glasses with yellow-tinted lenses that block blue light can help ease computer digital eye strain by increasing contrast. Anti-reflective lenses reduce glare and increase contrast and also block blue light from the sun and digital devices.
“Lighting color affects sleep, wakefulness: Green light promotes sleep while blue light delays it, find researchers.” ScienceDaily.
Safer : LEDs are much cooler than incandescent lights , reducing the risk of combustion or burnt fingers. Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
The worst thing that can happen is the LED Strip can get very hot and begin to burn whatever it is fixed to, if it is a flammable surface such as timber, the outcome can be disastrous. The other problem is running too much LED Strip linked together, or on under-rated wire or cable, this can also post a Fire Risk.
HOW LONG DO LED LIGHT STRIPS LAST? LEDs boast a general life expectancy of 50,000 hours . This equates to around six years of continuous use. Over time, LEDs slowly and gradually lose their light output and 50,000 is the number of hours it generally takes for LED lights to diminish to 70% of their original light output.
