9 LED Flashlight from Thrive Life
This is the information THRIVE Life provides:
This flashlight includes 9 LED lights for a super bright light with a long life. With an easy push on/off button and requiring 3 AAA batteries that are not included you'll be ready to go
So if your like me, a flashlight is a flashlight is a flashlight. Not actually true. One must actually decided what is to be the use of the flashlight. Obviously the most important thing is its functionality and usability and of course the light that it emits. No one flashlight will work best in all areas. But one of the major difference now days is the technology these flashlights have inside. And this technology consist of different types of bulbs which are currently on the market. I decided to do some research on the subject at hand. ( I have a bit of knowledge when dealing with Halogen and LED's due to one of my hobby's is saltwater fish. I have a 220 gallon salt water tank and a 55 gallon salt water tank. I have Halogen and LED's lights.) But in the end it should come down to your personal preferences based on the strengths and weaknesses of the bulbs. With that being said, the biggest differences are the amount of brightness, longevity of the bulb, runtimes, and the cost.
The following are choices you will encounter Incandescent Bulb Types or LED (Light Emitting Diode) Types:
(this information was provided by http://www.flashlights.com/how-to-buy/index.html )
Krypton Bulb – Incandescent bulb filled with Krypton gas. A very economical bulb, but usually
not as bright or long-lived as a xenon or halogen bulb.
Xenon Bulb – Incandescent bulb filled with Xenon gas. Provides extremely bright, white light.
Xenon bulbs are an excellent choice for long distance performance.
Halogen Bulb – Incandescent gas-filled bulb that blackens less when it ages than other type
bulbs. May have longer life than a xenon bulb of equivalent performance.
LED (Light Emitting Diode)
LEDs – A computer chip-like device that emits light when power is applied. The LED usually has a
built-in lens and projects a wider, more dispersed light. Their solid-state construction makes LEDs very durable and long-lived – up to 100,000 hours of life. LEDs do not require periodic replacement as do incandescent lamps. LEDs are good for close work because of their wide dispersion and soft focus.
Typically, LEDs provide much less power than incandescent lamps but offer the advantages of extremely long runtimes (up to 100's of hours at low illumination levels) unlike the much shorter runtimes of xenon or halogen lamps. Safer – solid state lamps make LEDs safer than incandescent in hazardous environments,
provided the flashlight has a hazardous location rating.
LEDs come in a variety of colors for different applications. White LEDs are the most popular for general
applications. Which color is right for you?
White – Most popular for all around use. Very close to natural light, which allows you to see "true
Blue – Extremely bright. Ideal for various industrial and automotive applications and has similar characteristics of a black light. Also commonly used in forensics.
Green – Extremely bright. Great for Hunters because it preserves night vision and won't spook game. Also, the International Hunter Education Association (IHEA) teaches students to associate a Green light in the woods as another Hunter.
Red – Ideal for signaling, pest control, and aviation applications. Best at preserving night vision, but does not provide as much usable light as does green. Insects cannot detect red light and it is ideal for pest control personnel.
High Flux LEDs – High flux LEDs provide the reliability of an LED with the performance of an
incandescent bulb and are the latest in high power LED technology on the market today. Provides a much greater light output than standard LEDs (10X's brighter) and can be focused with a reflector. High flux LEDs, like standard LEDs are durable and do not require periodic replacement like incandescent lamps –
expected lifetime of a high flux LED can be from 10,000 to 50,000 hours.
Combination LED/Incandescent – LED/Xenon combination lights combine the long runtimes and durability of LEDs with the brightness of incandescent. Arguably, the best of both worlds.
LIGHT MEASUREMENT – TWO BASIC METHODS ARE USED TO RATE LIGHT OUTPUT:
Candlepower (Peak Beam Candlepower) – A measurement of the brightest spot in the focused beam.
It is a function of both the output of the lamp and the efficiency of the reflector. The term "candlepower" (now candela) originates from an earlier unit, the "candle," and was based on the actual candle of specified dimensions and construction.
Lumens (Total Luminous Output) – A measurement of the total light output of the flashlight
regardless of beam focus. It is almost entirely a function of the bulb or LED.
Features between Halogen and Led:
(information obtained from the article at livestrong.com listed below)
A halogen light is an incandescent light with a tungsten filament, which is surrounded by an inert gas combined with halogen. Halogen is a type of nonmetal element such as iodine or bromine, both of which are commonly used. Both xenon and halogen lamps provide high output for their size and a white,
LEDs, on the other hand, do not have filaments. They are illuminated by the movement of electrons within a semiconductor material, which releases photons. The semiconductor contains two regions separated by a
junction that allow electrons to flow in one direction. LED stands for light emitting diode.
As an incandescent bulb, halogen lights resemble other filament bulbs very closely. They even tend to give off a lot of heat when an electrical current passes through the filament. However, LED lights do not
produce heat. They simply depend upon the position of the electrons within the bulb. If you desire a flashlight that does not give off heat, then you should buy an LED flashlight.
According to Sensory Metrics, a technology website led by a team of experienced professionals and former scientists from major companies, a 50 watt halogen bulb will produce about 1,000 lumens in full
brightness, which is a measure of the power of light as perceived by the human eye. A 2.5 watt LED will produce about 180 lumens. However, LED may actually appear a little brighter if both lights are dimmed to low levels.
LED bulbs have a much longer lifespan---many of them can last about 50,000 hours or more---while halogen bulbs will only last about 2,000 hours. Of course, this depends upon the wattage. A brighter bulb will
burn out faster, so a 35 watt halogen bulb will last about 1,000 hours longer than a 50 watt bulb. LED lights are more expensive, but over time you will have to buy fewer LED lights, which should allow you to save money.
You may purchase flashlights that use either LED or halogen technology. Halogen bulbs are often used in large, bulky and powerful flashlights. Both Halogen and xenon require periodic replacement and can fail on extreme impact. They are easily focused and are the most powerful, highest performance, top choices for
long distances today.
LEDs are still quite efficacious for lighting, but they are more dependable and built to last. Some flashlights actually combine the two types of bulbs, allowing the operator to switch between them and utilize the advantages of both. These bulbs are supposedly more energy efficient and are more durable when it
comes to shattering when the bulb is dropped. More and more flashlight companies are starting to use this type of bulb because it requires less energy from the battery to produce the brightness which means that the bulb lasts longer.
With all that being said, it still comes down to personal choice.....and expense....
