What is a 9 watt LED light equivalent to?
LED light bulbs take energy efficiency to another level, using around 40% less energy than CFL equivalents….LED equivalents to CFL light bulbs.
| CFL Light Bulb Wattage | LED Equivalent Wattage |
|---|---|
| 9 Watt | 5.5 Watt |
| 5 Watt | 3 Watt |
How do you calculate LED downlights?
A general rule of thumb for spacing your downlights is to take the height of your ceiling and divide by 2. For example, if your ceiling is 8 feet high, then your downlights should be around 4 feet apart from each other.
How many lumens is a 9W LED?
| LED Wattage | CFL Wattage | Lumens |
|---|---|---|
| 6W | 12W | 700 lm |
| 9W | 15W | 900 lm |
| 12W | 20W | 1,300 lm |
How is LED equivalent calculated?
Use this 5:1 or 6:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb. For example, if you wanted to replace a 60-watt incandescent bulb, what wattage LED bulb would be roughly equivalent? Using the 5:1 ratio, simply divide 60 watts by 5 to get 12 watts.
How bright is 9W LED bulb?
800 lumens
9W LED (800 lumens) replaces a 60W bulb or 14W CFL.
Is 9 watt LED bright?
The ThetaLux – 9 Watt LED Light Bulb is a great product. It is bright enough to provide sufficient illumination for reading or whatever you might want to do.
How do you calculate downlight spacing?
Recessed downlights are generally positioned 1.5 to 2 ft. away from walls with a space of 3 to 4 feet between each light. Dividing the ceiling height by two is a way of gauging how much space to leave between each downlight. Thus, if your ceiling is 8 foot high, place your lights 4 feet apart.
How are light fixtures calculated?
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.
What does 9W 60W mean?
A 9W light bulb has the same brightness as a 40W light bulb, whereas a 14W light bulb has the same brightness as a 60W light bulb.
How bright are 9W LED lights?
9W LED (800 lumens) replaces a 60W bulb or 14W CFL. 13W LED (1100 lumens) replaces a 75W bulb or 19W CFL. 17W LED (1600 lumens) replaces a 100W bulb or 23W CFL.
How do you calculate spacing?
Divide distance “A” by the number of spaces between objects. In our example, this is 223.5″ / 3 = 74.5″. This is the center-to-center distance of the posts (or flower pots on your porch, holes in your board, or pickets on your fence). The spacing between the objects is that distance less the width of your objects.
