When LED lights start getting deeper into their lifespan rating, the overall illumination quality can be dimmer than what it was when originally installed. The best products in the industry tap out at 35,000 hours. Most fluorescent light bulbs have a longevity rating that falls between 6,000 hours to 15,000 hours. Specialty products in this category are reaching six figures, with 200,000 hours a possibility for a state-of-the-art product. Most LED products have a manufacturer's rating of at least 50,000 hours. The following comparison chart outlines the various uses to consider with these technologies. It became more popular to have them in light bulbs in the 1990s and 2000s as this technology evolved.īoth options provide potential benefits when installed. Although others had produced similar technologies, he was the first to create a product that was both visible and practical. The first LED light bulb came from the mind of a 33-year-old scientist named Nick Holonyak, Jr. They offered different colors, including pink and blue. The MAZDA lineup of fluorescent lamps reached the market in 1938. This technology would slowly take over the incandescent light bulbs people used for the next few decades. This team took the research and knowledge from the previous decades to produce what would become the standard incandescent bulb. That's why credit for the invention falls to Peter Cooper Hewitt.Įven then, the vapor lamps from Hewitt are no match for what GE scientists created in 1934. Although the experiments proved that the technology was viable, neither inventor could create commercially viable options. The first fluorescent tubes came from the minds of Edison and Tesla in the late 19th century. You can purchase fluorescent bulbs or choose LEDs. Two primary options are available today if you have fixtures that require tube lights.

The Effective Lumens value will always be lower than the Raw Lumens value (sometimes by a huge amount) so care should be taken when comparing LED lights that you are looking at like-for-like outputs.Īll of our LED lights have their outputs stated in Effective Lumens (where manufacturer's data is available) and the higher the value, the brighter the light will be. However, once these chips are assembled into the lamp complete with the lens and housing there will be losses that reduce the actual light output, so a better measurement is Effective Lumens which takes into account these losses and tells you about the useful visible light that is produced. Raw Lumens is a measure of the theoretical maximum brightness of the LED chips themselves, based on the chip output and drive current. LED lights instead have their outputs stated in Lumens which is a direct measurement of brightness rather than power consumption. The problem with LEDs is that they use much, much less power than conventional bulbs for an equivalent light output, so using Watts as a measure of comparing brightness is no longer useful. This allows us to have a good understanding of how bright it will be as there is an approximate correlation between power consumed by the bulb (Watts) and brightness. Conventional lighting based upon incandescent filament bulbs is traditionally referred to as having an output in Watts.
