How do LEDs generate light?
By driving an electric current through a tube containing argon and mercury vapor
By moving electrons in compound semiconductors
By passing an electric current through a filament heating it up
By ionizing mercury vapor in a glass tube
LEDs generate light by moving electrons in compound semiconductors. This radiates lights when the current passes through the semiconductor diode in the forward direction.

Do LEDs prefer heat or cold?
Cold
Heat
As a rule, LEDs prefer cold. Heat negatively affects electronics, therefore making it a less suitable environment for LEDs and all other types of bulbs.

What CRI (Color Rendering Index) should you expect from an LED light?
60+
75+
80+
95+
You should expect a CRI of 80+ from an LED light. CRI, or color rendering index, is used to measure light quality on a scale from 1-100. The higher the rating, the better the light source can render color.

LED light bulbs produce about the same amount of light per watt as what other type of bulb?
Compact Fluorescent (CFL)
High Pressure Sodium (HPS)
Incandescent
Pulse Start Metal Halide (PSMH)
The latest LED bulbs produce about the same amount of light per watt as compact fluorescent bulbs (CFLs).

LEDs contain mercury.
True
False
LEDs do NOT contain mercury. LEDs produce light by moving electrons in compound semiconductors therefore eliminating the need for mercury.

What is the nanometer range for turtle lighting?
365nm-425nm
490nm-520nm
580nm-610nm
610nm-675nm
The nanometer range for turtle lighting is 560nm-590nm. Using a nanometer range of 560nm-590nm produces amber lighting which allows for turtles and other animals to follow the white light from the moon, rather than the white lights from parking lots, bollards, and other commercial lights keeping wildlife safe in coastal areas.
