Why Is Led Tape Light in Lumens?

Led Tape Light – Advertising light source in terms of lumens instead of watts has become a fairly common practice in recent years and this is largely due to the advent of energy efficient lighting technologies. Over the years, we’ve been shopping for light bulbs with their watts. While the lighting market is dominated by incandescent and halogen lamps, there is no problem. The direct correlation between the wattage and the brightness is set and, since the efficiency of the light source does not really very, it remains true regardless of the model. However, as soon as an energy efficient light source arrives, the wattage immediately loses its usefulness.

The problem is that watt is a measurement of the amount of electrical energy used by a bulb and does not give us information about the color or amount of light it provides. Because led tape light is capable of generating large amounts of light while consuming very little electricity, using watts to measure brightness becomes very difficult and drawing a direct comparison between LEDs and halogens is made almost impossible.

For example, a 4 watt LED bulb can produce the same amount of light as a 60-watt halogen. Simply put, the light output from the bulb can remain the same, even if the wattage varies, and vice versa. The efficiency of the light source can be worked out based on the lumen-to-watt ratio (lm / W), which, in other words, is the amount of light (lumens) released for each watt of electrical energy consumed. Most incandescent lamps reach about 17 lm / W, while CFL (Compact Fluorescent Lamps) can set between 35 and 60 lm / W. However, the typical led tape light will easily manage 160 lm / W, with some prototype models even reaching 200 lm / W is surprising.
