Do LED lights Attract Bugs and Insects? and Ten more Amazing Facts About Light Emitting Diodes or LEDs
Bugs Trapped in Light
1: LED Light Does Not Attract Insects*(does it?)
Are bugs and insects attracted to LED bulbs? It may not be so much the type of light bulb as it is the "COLOR Spectrum" emitted by the lamp you have chosen ; incandescent light emits a spectrum known as IR or infrared. Although not a useful bandwidth to the human eye, insects seem uncontrollably drawn to IR and blue spectrum light sources. “Bug Zappers” take advantage of this well known suicidal phenomenon to attract and kill nearby insects. By changing your front porch or even your interior lighting to “Warm White” LED Bulbs, insects from outside will be less likely drawn onto or into your home. Insects are however drawn towards the blue spectrum.
*LED lights with color temperatures of 3200k or higher (cool white) will definitely attract insects.
“We have a large property and I replaced 38 fluorescent t8 tubes and about 20 light bulbs and 4 flood lights with LED equivalents. I ordered different types / brands and light colors which are measured in K. It is obvious here in our part of the world that certain LED light colors ( warm) attract much less insects than some cool color lights. As not all insects are the same, some might be still attracted to warm LED lights as they might be equipped with different sensors. But one thing is for sure, certain "warm" type LED lights are almost “insect free” at night here.”

2.LED Based Spaceship Engines?
While intense light itself cannot offer sufficient thrust to propel a craft through space, "UV photo acid generators that are suspended in polymer gel base material", combined with high output LED arrays can offer stable solid-to-gas fuel supplies for extended journeys. Advancements in photo reactive gas emitting polymers, layered with ultra-efficient Ultraviolet LED Arrays, may be an effective propulsion system for a large spacecraft.
3: LEDs Proven to Keep Meat Fresher in Delicatessen Displays
Recent scientific observations worthy of mentioning, researchers found lower bacteria levels in meat displayed under LED lighting. The exact reason for this effect is still under investigation. Store owners and clothing resellers realized long ago, displays under halogen lighting often suffer damage from ultraviolet and infrared radiation (UV rot) as well as from heat generated from the lights.
4: LEDs Emit Little Heat and No Ultraviolet/Infared Radiation
Today’s high output LEDs need to move heat away from sensitive LED circuits, and into (commonly aluminum) heat-sinks. The transfer of this heat can make the housing of the LED warm to the touch. Objects even inches away from (or in) super bright LED light beams, do not become warm to touch, there is no heat transferred along with the light such as found with incandescent. This greatly reduces potential of fire risk associated with traditional lighting.
5: LEDs Run Brighter and More Efficiently the Colder it Gets
Compact fluorescence are known to operate poorly in colder climates and energy efficiency for other types of lighting also drops coinciding with temperature decreases. LEDs and their accompanying fixtures are designed to run at nominal temperatures, when exterior temperature drops the cooling of the LEDs becomes ultra efficient resulting in increased brightness.
6: LEDs are Crystal-Based Lighting Technology
Other than incandescent light bulbs, most of today's lighting technology relies on mercury, a known neurotoxin listed by the World Health Organization as
“one of the 10 groups of chemicals of major public health concern.”
Manufacturing, accidental breakage, and disposal of these products have become an environmental concern of enormous proportion. LEDs on the other hand, emit electro-luminescence., contain no mercury, lead or other environmental toxins, LEDs are composed of Non-Toxic, Nano-Crystal layers, covered by a phosphorus coating.
7: LED-Based Weapons
Shining bright lights into people's eyes has been used as a form of soft torture for many decades (think of the old interrogator tilting the hanging light into the interviewee's face). Fast forward to today's tactical flashlights, these LED-based ultra bright weapon mounted searchlights, have a disorienting strobe function that basically destroys the retina of the targeted victim, rendering them immediately incapacitated and temporarily blinded.This Non-Lethal weapon is featured in a scene from the action thriller "Hanna," (starring Saoirse Ronan.2011)
8: LEDs Helping Babies Fight Jaundice
Light has been long known for its therapeutic and healing capabilities. NASA has been studying the effects of LEDs for healing wounds incurred in space. For the first time physicians and healthcare workers are now able to offer babies LED light therapy without concern of the associated infrared radiation or drastic increases in temperature.
9: LED for Growing Coral
LED has been widely accepted for Marine aquarium applications. Growing coral in a tank is a difficult proposition; LEDs have helped aquarists achieve sufficient light levels without overheating the surrounding water. Low-voltage LED lighting is becoming a more popular choice for aquarium use, for both safety and efficiency reasons.

10: LEDs Use Between 50%-80% Less Electricity
Today, a commercially available LED 8 W bulbhas the same luminary output as its 50 W incandescent or halogen counterpart. LEDs are the most efficient light source available today, because of their high-tech components; LED bulbs sell for many times the price of standard “Edison type” bulbs. A recent Consumer Reports analysis concluded “Even an $80 LED bulb pays for itself in energy savings over the stated lifetime of the product.”
Consider that it takes "approximately 714 pounds of coal to power a 100 W incandescent lightbulb 24 hours a day seven days a week for one year."
“There are nearly a billion, 60-100 watt lightbulbs thought to be in use across North America in use at any given time “
LED continues to demonstrate advancements in technology and manufacturing, making LED the obvious choice for long-lasting, non-toxic, energy efficient solid-state lighting solutions that can drastically reduce the amount of coal burned each year to provide lighting.
