Led Bulb Incandescent Equivalent

That incandescent bulb was only rated for 1 500 hours or 1 4 years.

Led bulb incandescent equivalent. Incandescent bulbs generally generate a yellowish warm white colour with a cct of around 2700k and a cri of 100 as incandescents are the reference light source used in the cri metric. It used to be that you could buy a 60 watt incandescent light bulb for less than a dollar. An important safety consideration. The energy consumption to use a bulb like this would cost about 90 over the course of 10 years.

Now you can buy a 4 pack for about 6. While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs. Led lights offer a much broader range of colour temperatures ranging from warm white to natural sometime s called pure or daylight white to a bluish. But here is the math.

The prices are coming down as production ramps up. To examine the cost comparison let s take a look at a standard 60 watt replacement incandescent bulb in this example. However because lumens per watt vary for both incandescent and led lights it s easier to use a wattage to lumens comparison chart. For an led running over the course of 10 years the actual cost would be only 18 to operate.

In fact a 60 watt led just may blind you. On average an incandescent bulb produces around 14 lumens per watt compared to 63 lumens for energy saving compact fluorescents cfl and 74 for led bulbs. A 40 watt incandescent filament bulb produces. For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.

Some of the most energy to light efficient led bulbs are now reaching over 120 lumens in energy star tests. Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens. In this style led bulb clusters of leds are covered by a lens which spreads the light over a wider area like standard incandescent bulbs. If a fixture is rated for a certain wattage use the equivalent lumen rating in the chart above when deciding what size led bulb can be used in that fixture.

When the bulbs first came out to buy a 60 watt equivalent led would cost 10. Available in standard edison bases these bulbs are used as area lighting for rooms porches reading lamps accent lamps hallways and low light applications where lights remain on for extended periods. For example if you typically purchase 60w incandescent bulbs which produce about 700 800 lumens consider purchasing a lower energy alternative like a 42w halogen bulb 12w cfl or even a 10w led bulb to achieve the same brightness.

An led that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. Wattage to brightness comparison.
