Anatomy of an LED strip. An LED strip light is typically half an inch ( mm) in width, and up to 16 feet (5 meters) or more in length. They can be cut to specific lengths using just a pair of scissors along the cutlines, located every inches.   In LED lighting, lumens measure the brightness of a light. This is different than Watts, which measure the amount of energy in a light. The term lumen means “light,” which makes sense when you understand what this measures. In other words, lumens measure the amount of light your LED light . A single light fixture stocked with a watt incandescent bulb consumes about kWh of electricity in a year; put a GeoBulb LED bulb in that light fixture, and the annual energy use is more like 65 kWh [source: Sundance].The annual CO 2 reduction is in the hundreds of pounds for a single lamp.. But energy-efficiency is just part of the story.

LED drivers can be a confusing part of LED technology. There are so many different types and variations that it can seem a little overwhelming at times. That’s why I wanted to write a quick post explaining the varieties, what makes them different, and things you should look for when choosing the LED driver(s) for your lighting application. for evaluating LED fixtures and for making accurate comparisons to conventional fixtures. Describes how much ‘Useful Light’ a fixture can deliver to the task area. ‘Useful Light’ is the portion of a fixture’s output that is effectively delivered to the task area, discounting any wasted light. Lumens are the measure of total light intensity from a single source (in this case, a tube). The greater the lumens, the brighter or more intense the light. A watt fluorescent tube, for example, is rated around lumens. To replace it with the same intensity LED, just look for one that rates around lumens. Basics; Understanding LED Technology. LEDs may be little, but new high-brightness models are producing a considerable amount of light. First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six years.

How To Buy LED Bulbs for Your Home. Lighting your home or business comprises around 15% of your overall energy bills. On average, $ is spent each year to light your home. These numbers may not seem like a lot, but consider this—you can cut that expense in . Lumen maintenance is an approach of measuring the light output (lumens) of a brand new light source and comparing that with its light output after a certain period of time. L70 and L50 are examples of lumen maintenance – benchmarks for when 70 or 50 percent of a lamp or fixture's total light output remains. Chances are, the LED will light briefly and then go out for good, but the LED may also melt, make a mess, and smell up your house.
