Product Information

A properly lit room should have between five to seven light sources. And ideally, they should be a mix of different types of lights, positioned throughout the room at varied heights and. By combining floor lamps, table lamps and wall lamps, it'll be easier for you to create perfect lighting and help your room come to life. Use height when deciding on indoor lighting

Instead, you want to work with light at different levels. For example, you can have one or two table lamps in your window at mid-level, then a wall lamp placed in a higher position, together with a floor lamp that ends up somewhere in-between. That way, the light is more dynamic, making your room look bigger and more interesting. Indoor lamps need darkness to shine In basic terms, Lumens (lm) are a measure of how much visible light is emitted by a light source, this is described technically as its luminous flux. The total power of the visible light is represented by the total number of lumens given off. In short, when looking for the power of the lamp within a lighting fixture, look for the total number of Lumens. LUX The candela (cd) is the standard unit of luminous intensity or brightness of a light in a specific direction. The name candela is derived from the fact that a common candle produces approximately 1 candela of brightness in a given direction. The candela is mostly used when dealing with focused light, such as a torches or spotlights, and as such often isn’t stated on luminaires.The best bedside table lamps should cast a soft glow over your bedroom. Too bright and they could make it harder to fall to sleep. You should also consider how big your bedside table is, as a large lamp will look out of place on a small cabinet. Touch bedside lamps are ideal when you need to simply switch off and sleep.

In addition to light itself, there are other factors to consider when measuring the amount of light emitted. Most lamps are encased inside a light fitting consisting of elements such as diffusers and reflectors. These elements, along with things including the shape and number of lamps, will have an effect on the brightness and distribution of light from the luminaire. Luminaire efficacy factors these elements in to give a more accurate measurement of the lumens given off by the entire luminaire, in a fully assembled state. LUMENS PER WATT Lumens, Lux, Watts? Here is our simple guide to some of the basics in understanding how brightness and light are measured in modern electric lighting. WATTS Lux (lx) is used to measure the amount of visible light (luminous flux) spread over a surface area, this is known technically as illuminance. Illuminance is a fundamental consideration for lighting designers and architects when specifying luminaires for an installation. Another way of expressing this unit is as lumens per square metre, as 1 lux unit equals 1 lumen per square metre, or 1 lx = 1 lm/m2. In buildings, lux can be measured with a device called lux meter which will give an accurate reading of the illuminance. LUMINAIRE EFFICACYWhite light is the most common and while this can be very effective, there is some research to suggest blue light treatment can also work well. Some models have an additional red light to help you relax and unwind at the end of the day.
