To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement . For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.

Multiply width of room x length of room x 1.5 = amount of total minimum wattage needed (assuming an eight foot ceiling). Divide by 60 to get the number of 60-watt equivalent bulbs required. Then, add up the wattage in each bulb in each fixture to figure out how many light fixtures are needed.

For a bedroom, look for a light bulb that has a lumen rating of around 800, which is roughly equivalent to a 60-watt traditional incandescent bulb, or lower . At this brightness level, you'll have enough light to read by, but it won't make you feel more alert when you're winding down at bedtime.

Multiply the width by the length for each room or room segment, if applicable. Multiply the result by 1.5 to determine the estimated watts to sufficiently light a room . For example, for a room 10 feet wide by 12 feet long, multiply 10 times 12 to get 120, then multiply by 1.5 to get 180 watts.

Multiply the width by the length for each room or room segment, if applicable. Multiply the result by 1.5 to determine the estimated watts to sufficiently light a room . For example, for a room 10 feet wide by 12 feet long, multiply 10 times 12 to get 120, then multiply by 1.5 to get 180 watts.

1000 watt equivalence LED can offer 130 to 200 lumens per wattage . Besides, LED power supply driver has 95% transferring rate, which means very high conversion rate. The actual lumen for LED is 95-190 lm/watt which is 200% to 300% higher than metal halide.

1000w LED fixtures generally have an output equal to 900 watts of HPS light , despite what many manufacturers claim.May 29, 2022

For each MH the lumen efficiency is almost 60 to 110 watts. So, a 1000 watt metal halide bulb can produce 50,000 lumens to 100,000 lumens . Similarly, a 400 watt bulb of metal halide produces almost 24,000 lumens to 44,000 lumens.

LEDs often require a certain amount of volts, depending on the type and color of the LED. Most experts recommend 2-3 volts for LEDs. However, you can look it up to be certain. This article explains what happens if you put too much voltage through an LED and how to prevent such a situation.
