This is very bright for indoor lighting, the equivalent of about 350 watts of incandescent lighting, or a 65-watt and 42-watt CFL pair (4200 and 2700 lumens respectively).
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
The main types are: Incandescent 10 lumens per watt Halogen 13 lumens per watt Fluorescent 40-50 lumens per watt LED 40-60 lumens per watt Lumens measures the brightness, watts measures the electric power used.
About 80 lumens per watt of electric power is normal for LEDs.
The actual amount of light (lumens) given off by a bulb depends on the how the bulb was made and with what materials. It depends on the filament material, its length and thickness, and the type of gas in the bulb. As a rule, longer lasting bulbs of the same wattage will generally be less bright than others and brighter bulbs of the same wattage will not last as long as other bulbs.Sample lumen outputs:Sylvania 250 Watt Indoor Soft White 3-Way Bulb can emit 3940 lumens at its highest setting.Philips 250 Watt 120 to 130V PAR38 Krypton Flood Bulb emits 3100 lumens
A 150-watt light bulb uses energy at the rate of 150 watts, when it's turned on.
one lightening candle is one lumens, 120 lumens is 120 candles togher. Like IMALENT 4000Lumens, DDT40,imagine how it is bright.
Yes, 1000 lumens is considered bright, and it is suitable for lighting up a room or outdoor space effectively. It is a common level of brightness for flashlights, light bulbs, and portable lanterns.
High Bright: 1700 Lumens Eco Mode: 1360 Lumens http://www.infocus.com/Support/Products/Projectors/IN24.aspx
It is equivalent to a 75 watt incandescent bulb
3300 lumens is considered fairly bright, suitable for lighting up a medium-sized room or outdoor area. It is equivalent to the brightness of a traditional 200W incandescent light bulb.
2600 lumens is considered quite bright for a light source. It is roughly equivalent to the brightness of a 150-watt incandescent bulb, making it suitable for illuminating large spaces or outdoor areas.
Well friend, lumens and watts measure different things. Lumens tell us how bright a bulb is, while watts tell us how much energy it uses. A 35 lumens bulb may not be as bright as a 60 watts bulb, but it can still light up a room beautifully in its own gentle way. Just remember, every light has its own special glow that can bring warmth and comfort to any space.
it is hard to describe by words, why not to buy an infinite bright flashlight to compare. I know a flahslight with displaying lumens. It is DDT40 imalent. from 5 lumens to 4000 lumens you could find a way to compare gradually. by the way, one lightening candle is a lumens.
Mitsubishi HC3900 with 3000 ANSI Lumens....best!
Yes, 650 lumens is considered bright for most indoor lighting situations. It is equivalent to about a 50-60 watt incandescent bulb and can provide ample illumination for a room.
The 3M 2000 has a brightness of 1,600 lumens, which should be bright enough even in moderate daylight.
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
