Incandescent.
What does lumens mean in light bulbs?
Lumens, not watts, tell you how bright a light bulb is, no matter the type of bulb. The more lumens, the brighter the light. Labels on the front of light bulb packages now state a bulb’s brightness in lumens, instead of the bulb’s energy usage in watts.
How long do LED lights last?
Both CFL and LED light lamps will last longer than the incandescent model. When it comes to maintaining a CFL vs. LED lamp, however, experts again agree that you will likely need to replace the CFL model more frequently. In fact, the typical CFL has a lifespan of roughly 10 years. By comparison, an LED is expected to last at least 15 years, with some models exceeding 25 years. At roughly 1.5 (or more!) times the lifespan of a CFL, the LED will need to be replaced far less often.
What is a light bulb made of?
Years ago, the standard light bulb was made of a tungsten filament and inert gas surrounded by a glass enclosure. Known as an incandescent light bulb, a metal stem at the base of the glass structure allows an electrical current to trigger the filament and provide lighting. In 2014, however, incandescent bulbs over 40 watts were discontinued.

LED vs CFL Light Bulb Differences
Energy efficient LED and CFL bubs have taken the market by storm due to their ability to conserve energy and longer lifespan. However, there is still a notable difference between the two bulbs which may make you prefer one over the other. The following are their main differences:
Light Emitting Diode Light Bulb (LED)
LED stands for light emitting diode. A diode is a semiconductor material with two terminals (an anode and a cathode), through which current flows in one direction only. Silicon is an example of a metalloid material that only allows electric current to flow through under certain conditions of temperature or pressure.
Compact Fluorescent Lamp (CFL)
CFL stands for compact fluorescent lamp. This type of bulb produce light when an electric current is sent through a tube containing argon gas and a small of amount of mercury. This generates invisible ultraviolet light that stimulate fluorescent coating on the inside of the tube, which then produce a visible light.
What is the difference between Watts and Lumens?
The WATTS is a measure of the amount of energy used by bulbs and the LUMENS is the measure of brightness provided by a light bulb (the higher the lumens the brighter the bulb).
Which is better, LED or CFL?
While the math for the CFL bulbs is simple, the LED bulbs are even more energy-efficient and durable than compact fluorescent light bulbs. LEDs require less wattage than CFL for the same amount of light.
Why do CFLs reflect back into the ceiling?
When CFLs are placed in certain fixtures, such as recessed types, much of the light they produce only ends up being wasted; light is reflected back into the ceiling because CFLs are multi-directional.
What is a lux candle?
Lux or foot candle - Is a measurement of a lights strength or brightness taken from a surface. A light bulb lux is measured using a lux metre. Luminous efficacy or lumens/watt - The number of lumens generated by a light bulb relative to the energy it consumes.
How to calculate luminous efficiency?
The more light a bulb produces for every watt, the more efficient it is. To compute a light bulb's luminous efficacy, simply divide its total lumens by its wattage. Bear in mind though that this can be inaccurate, as manufacturers often have different ratings for their products.
What is the difference between LED and CFL?
The inherent design of LEDs makes it give off directional light. Unlike incandescent, compact fluorescent (CFL) and halogen bulbs which have a very wide beam range, LEDs have a narrower lighting angle and are thus best suited as spotlights.
What is lumen in LED light?
Lumen - As explained earlier, a lumen is a unit of measurement used to describe the amount of light generated by a light bulb.
What is the measure of the brightness generated by a light bulb?
A Lumen is the measure of the brightness generated by a light, as seen by the human eye. This unit of measure is indicated on the packaging of most light bulbs. Another measurement often associated with light bulbs is lumens/watt.
Do CFLs have lumens?
If you look at the packaging of CFL and LED light bulbs, you can see that CFLs will almost always have a slightly higher lumen/per watt rating. However, luminous efficacy isn't only determined by the number of lumens generated for every single watt a bulb uses.
