Tips for Buying LED Bulb

There are several varieties of residential LED light bulbs on the market. Presently, LEDs best replace track lighting and flood lights, both of which take advantage of the directional nature of LED light. Below are some tips for buying LED light bulbs.

• The Basics
You want to find an LED bulb that produces a healthy amount of light, but at the lowest possible power consumption. A good metric that equalizes your search is “lumens per watt”. To derive this figure, simply divide the bulb’s number of watts into the number of lumens. Right now, a good LED bulb should have at least 40 lumens per watt, but preferably more.

The question is often asked about comparisons between normal light bulbs and LEDs. Here are some examples to guide you:
5-watt, 3 high power CREE LED, MR16 ~ 25-watt MR16 Halogen
5-watt, 3 high power CREE LED, E27 spot ~ 30-watt E27 spot Halogen
6-watt, 165 traditional LEDs, PAR38, ~ 50-watt PAR38 incandescent

• Lifetime of Bulb
Many manufacturers of LED bulbs claim lifetimes of 50,000 hours to 100,000 hours. The lifetime of an LED lamp is generally considered to be the point where the light output has declined to 70% of it’s initial output, measured in lumens. So, a 300 lumen LED bulb with a lifespan of 50,000 hours will have 210 lumens at the end of it’s lifetime. However, the lifetime of a bulb does not mean it is unusable, only that it’s light output has degraded to a certain point. The LED bulb may continue to be useful for several thousand hours past it’s stated lifetime. Unlike old-fashioned light bulbs, it is extremely rare for an LED light to simply burn out. Rather, it will gradually fade over time.

• Color
As a general rule, you should use warmer light indoors, and whiter light outdoors. A color temperature of 2500-4000 Kelvin works great indoors. You should use a bulb with a color temperature of 5000-7000 Kelvin outdoors, as the whiter light allows your eyes to see better at night.

White light in the 5000-7000 Kelvin range is also excellent for display cases, boutiques, artwork, or other settings where you need excellent color rendition.

• Type of LED lamp
LED light bulbs use one or more tiny semiconductor lamps to produce very focused light. Contrast this with normal light bulbs that generate light in all directions. LED lamps are currently available in two forms: traditional LEDs (typically 5mm), which are smaller, and high power LEDs. Light bulbs using traditional LEDs require a large number of LED lamps to produce sufficient light, whereas high power LED bulbs use one or more lamps to generate light.

In general, the more LEDs, the better the light dispersion. Always get LED bulbs with more than one LED. You will find that single LED bulbs produce a very conspicuous outline, similar to a halo. Unless you enjoy halos across your walls, it’s better to buy light bulbs with multiple LEDs.
