Product Information

A SAD lamp, light or light box uses light therapy to help improve your mood. They produce very bright lights to recreate the morning sunlight that you miss during the winter months. This ratio is basically the number of lumens a light gives off for each watt of power it consumes, referred to technically as luminous efficacy. As an example, a light emitting 1,000 lumens that consumes 100 watts of power, would offer 10 lm/W. Most lighting manufacturers will provide a lm/W figure on their luminaires and lamps as a guide to their overall efficiency. CANDELA It’s got a handy stand that enables you to position it either portrait or landscape, and a nice big surface area too, making it feel almost like you’re sitting next to a window that’s being flooded with bright sunlight. The only catch is that there’s no option to adjust the brightness setting – you’ll just have to sit further away if you find it too much. Overall, though, it’s difficult to ask much more from the Vitamin L when you consider its relatively low asking price. If you’re looking to buy your first SAD lamp, look no further. White 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. Pop the light on your desk if you're experiencing an afternoon slump, take it with you into the kitchen if you're in need of some energy while cooking dinner, or switch it on if you're feeling lethargic while doing chores such as sorting through life admin or reorganising a wardrobe – a SAD light could be the best investment you make this winter.

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 LED lights have been proven to work just as well as traditional tube bulb devices, but neither is considered superior to the other. What features should I look out for? You should look for one that provides enough light to see what you’re doing, but not so bright that it causes you to squint. We have a huge range of task lighting available in store and online, including the classic FORSÅ collection, LED-powered YPPERLIG table lamp, and RIGGAD, which comes with a wireless charging pad in its base.

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 The Lumie Vitamin L is one of the most energy-efficient SAD lamps around, but the biggest selling point for most people will be the fact that it emits a slightly softer light than other SAD lamps. A treatment of 20-30 minutes a day at 10,000 lux from a distance of 20cm should help lift your mood, or you can sit at arm’s length for an hour or two while using your computer to get the same effect. To help you improve the lighting in your home, we have everything from ceiling to floor lamps, as well as all of the in-betweens. A lamp here, a lamp there 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 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.

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. You want to make sure your lighting is positioned at varying heights. If not, your lamps might create an unflattering circle that directs all light towards the middle of the room. This can make the room feel smaller. 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 EFFICACY 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 shineIn 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 Focused task lighting relieves stress on your eyes, compared to relying on a single, main light in a room. You should also give some consideration to the kind of bulb you’ll use with your desk light. is one of our favourite large table lamps. With its tall, sophisticated and timeless design, it will suit all sorts of bedroom, hallway or living room designs. And you can combine a few for a unified look throughout the home. And for something a little different, our frosted glass table lamps, like GRÖNÖ and TOKABO, will provide a soft, warm glow. The light produced is measured in lux and a good SAD lamp will offer a brightness of around 10,000 lux. It's believed that SAD lamps encourage your brain to produce less melatonin, which makes you sleepy, while increasing the production of serotonin, which affects your mood. So how does a SAD lamp work?
