This is an initial criterion for choosing. It is possible that a 100 watt incandescent bulb produces less lumens as compared to a 10 watt LED produces more Lumens. A lumen is simply 1 unit of light output. No one wants to call electrician to replace bulb in busy season. All Rights Reserved. To start, all you need to do is multiply the length of the room in feet by the width of the room in feet. LumensA measurement of light emitted by a source, whether it’s LED, Fluorescent, Halogen, or Incandescent. So we need total of 20W LED light to get 2000 lumens and 150 Lux for our sample bed room. For example, a standard 60-watt light bulb produces around 800 lumens of light. Each type of ligh… This result is valid for houses containing rooms whose ceilings are 8 feet high. For a room with few/no windows, balance the 60 watt desk light with ambient overhead lights or bump that number up to 75 watts. Now that doesn’t mean go out and buy a 1000-Watt equal LED to light your living room like an x-ray. By the time you're 60, you need around 100 watts.” As brightness is measured in Lumens, the following will help you choose a bulb with the wattage (or equivalent wattage) that you need. In the case of modern homes having higher ceilings than 8 feet, the rule of thumb for the calculation is 1.25 watts per cubic foot. Living room needs more light than bedroom.

Notes: Step-by-step information on how to calculate power supply requirements. Step 2: Determine the voltage and watts per foot (or meter) for the LED strip. Secondly, even if we know how many radiometric watts a UV lamp produces, we do not know how and where the UV energy is distributed. Multiply the width by the length of the room and multiply the result by 2.5 to estimate higher light-level requirements. Example: What power supply wattage is necessary to power 10 feet of the 24V LED strips? For general purposes, 40 watts is enough. In the past wattage determined how bright a light bulb would be, were more wattage meant more brightness. Buy 12 Watt LED Bulb Set Of 4 For Just Rs.398.
