What is the CFL equivalent to 40W?
What is the CFL equivalent to 40W?
9 Watt
9 watt compact fluorescent spirals are excellent replacement for up to 40 watt incandescent bulbs. These bulbs emit about 550 lumens, use one quarter of the energy and last up to 5 times as long.
What is 40 watt LED equivalent to incandescent?
Equivalent Wattages and Light Output of Incandescent, CFL, and LED Bulbs
| Light Output | LEDs | Incandescents |
|---|---|---|
| 450 | 4-5 | 40 |
| 750-900 | 6-8 | 60 |
| 1100-1300 | 9-13 | 75-100 |
| 1600-1800 | 16-20 | 100 |
How CFL rating is equivalent to incandescent lamp?
Remember this rule of thumb: CFLs use about a quarter of the wattage to produce the same light. So to replace a traditional 60-watt bulb, buy a 15-watt CFL: 60-watt incandescent / 4 = 15 watts.
What is a 40W incandescent bulb?
The information below shows the typical Lumen levels expected from traditional incandescent bulbs. 40w incandescent = 380 – 460 Lumens. 60w incandescent = 750 – 850 Lumens. 75w incandescent = 1100 – 1300 Lumens. 100w incandescent = 1700 – 1800 Lumens.
What is an 11W energy bulb equivalent?
Buyers of the main type of energy-saving bulb, compact fluorescent lamps (CFLs), are told on the packaging that they shine as brightly as an old-fashioned bulb. For example, an 11W CFL is labelled as being the equivalent of a 60W incandescent bulb.
How many lumens is a 40 watt incandescent bulb?
450 lumens
Watts to Lumens – Energy Output to Brightness Produced 40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households)
What is 40 watt LED equivalent to?
Energetic LED bulbs are very solid replacements for 40 watt incandescent lamps. They are approximately the same size and shape as standard incandescent lamps, so there’s no worrying about whether this will fit into a particular lampshade or fixture.
Can I use a 60 watt CFL in a 40 watt lamp?
Yes, you can use a compact fluorescent (CFL) bulb that produces more light as long as it doesn’t exceed the wattage recommended for the fixture. Light bulbs are commonly compared using both watts and lumens. Watts are the amount of electricity used by the bulb while lumens measure the light produced.
How many lumens is a 40-watt incandescent bulb?
How bright is a 40-watt bulb?
A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb. Typically, the higher the wattage, the higher the lumens, and the more light output.
What size LED bulb can I use in a 40-watt fixture?
And some bulbs are marked not for use in fully enclosed fixtures. So long as the bulbs are not marked for limited use, you can generally use an LED bulb that is rated much higher than an incandescent bulb. In general, there is no problem using a 75W equivalent LED bulb in a fixture marked 40W maximum.
