Want a better night's sleep?  Did you know the light bulb that's been in your bedroom lamp might be getting in the way of your body making melatonin - the hormone that helps you fall asleep? The GOOD NIGHT LED light bulb, originally developed for NASA astronauts on the International Space Station, lets melatonin do its thing and helps to regulate your body's natural circadian rhythm.

Lighting Science 9 watt GOOD NIGHT A-19 dimmable 2400K LED bulb generates as much light as many 65 watt incandescent bulbs.

  • No lead or mercury means easy and environmentally safe disposal

  • Supports your body's natural melatonin production - a hormone necessary for a good, natural night sleep

  • Helps to promote a healthy circadian rhythm by assisting you in falling asleep faster, staying asleep longer, and getting a more restful night sleep

  • Very long life - Rated to still put out 70% as much light after 25,000 hours of operation as it does when brand new

How To Use?

  • Limit the use of electronic devices, media and all other light sources up to 2 hours prior to bedtime
  • Place the GOOD NIGHT light in areas of your home that you frequent before bedtime, such as a bedside table
  • Turn off the GOOD NIGHT light before falling asleep. For optimal sleep, total darkness is recommended. Utilize the GOOD NIGHT light at the same time nightly for optimal effect

Not recommended in fully enclosed fixtures because heat buildup will shorten life. Do not "hot swap" this bulb. Turn off fixture before replacing existing bulb.

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
 
Energy Used
9 Watts

Incandescent/Halogen Equivalent

The wattage value of an incandescent or halogen lamp of similar brightness.
 
Incandescent/Halogen Equivalent
65 Watts

Volts

A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.
 
Volts
120

Base

The end (or ends) of the lamp that fits into the socket.
 
Base
Medium (E26)

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
 
Bulb Shape

CRI

Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
 
CRI
80

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
 
Color Temperature (Kelvin)
2400

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
 
Brightness (Lumens)
650

Bulb Finish

The surface finish of a bulb, which may affect the quality of the light emitted.
 
Bulb Finish
Frosted

Bulb Technology

The technology implemented by the bulb, e.g. incandescent, halogen, LED

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
 
Average Rated Life (hr)
25000

Operating Temperature (°F)

The ambient temperature in which the product can safely operate.
 
Operating Temperature (°F)
-4 to 104

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
 
Length (in)

Does nothing that I can tell

As far as I can tell this bulb does nothing to help induce sleep. I have two of them and they are on all night, so they have every opportunity to work if they're going to.
