How to choose a chandelier with LEDs

With the development of technology we have more and more new interesting devices and appliances, and old and familiar ones acquire new functions and opportunities. For example, it has become fashionable to buy LED lights. There are two significant reasons for this – their diverse design and cost-effectiveness. About what properties have LED chandeliers for the home, how to choose them and we will talk further.

Features of LED chandeliers

All the characteristics, advantages and disadvantages of this type of lighting devices are due to the fact that LEDs are used as light sources in them. It is they that determine their properties and capabilities.

Diverse design

LED, even quite powerful – a small crystal, the size of a few millimeters, and it can produce a powerful light flux. Some crystals of 3 * 3 mm can replace not too powerful incandescent lamp. Another thing is that such crystals are expensive. But they can work for decades if the operating conditions are met.

These properties – a significant power of light flux at a small size – expand the design possibilities to infinity. When developing the design of all other lamps designers have to come up with some plafonds, and quite large in size – to be able to hide the light source.

When working with LEDs designers have virtually no restrictions – millimeter light sources can be placed in any order, quantity. “Plafon” for them is not required, since there they are with a different angle of dispersion. Even if you make a plafon, the approach is mainly aesthetic, the technical requirements are minimal. In this regard, the style execution is very different – from the usual classics to advanced high-tech, minimalism, loft. You can find any style.

Adjustment possibilities: brightness and glow temperature

Most light bulbs can only produce light of a certain spectrum (color). Incandescent and halogen lamps give only white light, some other colors can give only fluorescent, and even then not too much.

LEDs are arranged so that they can produce light of any color. This is their property is used in LED chandeliers with remote control. They use three crystals as a light source – red, green and blue. Changing the brightness of the luminescence of each of the bottom get any color of the spectrum. That is, LED chandelier for home can shine not only white light (with different shades), but also blue, green, red, etc. Note that not all models have this possibility, but only some.

Have LED chandeliers for home and another feature – the brightness of the glow can be adjusted within wide limits. This possibility is realized on the basis of incandescent lamps, for which special devices are used – dimmers. They decrease/increase the voltage, on which depends on the level of luminescence of the lamps. To change the brightness of light using a dimmer, you need to go to it (usually built into the switch) and turn the knob. With fluorescent or halogen lamps even this “trick” does not pass, they can not work at low voltage.

LEDs change the level of luminescence in a wide range and realize this function can be remotely – with a remote control. Change the amount of light can be both white and colored crystals. This function can be very convenient for children and bedrooms – you can not turn off the light, but only dim it to acceptable values.

Power supply parameters and service life

LEDs operate from a constant voltage of 12 V, while in the network we have alternating 220 V. For direct connection to the household network in lighting devices of this type are built into the voltage converter, which rectifies and reduces the voltage to the required values. From the quality of this converter depends on the life of LEDs – the more stable power supply, the more LEDs will last.

In general, LEDs can operate without significant change in characteristics for 30-50 thousand hours. This is equivalent to 20-50 years of operation. But this – only if the voltage is supplied within the specified limits.

Unfortunately, the power supply in our networks is far from stable. There are sharp spikes both up and down. Such spikes negatively affect the life of LEDs – they burn out, lose brightness. Since the LED chandelier – the device is far from cheap, it makes sense to supply power through a stabilizer. This, of course, an additional expense, but the stabilizer, creating normal conditions for LEDs, many times will extend their life.

Saving on electricity and low heat generation

LED lighting devices are characterized by increased efficiency – a lamp that consumes 15-20 watts of electricity, light is given out as much as a 100W incandescent lamp. This is due to the fact that the LED most of the consumed energy is spent on glow and only a small part of it is converted into heat. At the moment, this is the most energy-efficient light sources.

The low amount of heat generated by LED chandeliers for the home allow them to be used for stretch ceilings.

LED chandeliers for the home: choice

When choosing an LED chandelier for the home, in addition to aesthetic criteria and size, you need to track some more technical points:

These are the technical characteristics that must necessarily be monitored. They are even in the brief description of the product. At any rate, there should be. If you do not find some data, it is better to look for something else. The quality of this one is unlikely to satisfy you.

Features of the choice of chandeliers with remote control

LED chandeliers for home and office with remote control have their own features. In addition to all the technical characteristics described above, you still need to check:

• What exactly are the options that this model has. May be:
• The range of the remote control. For small rooms it is not so important, but for spacious rooms – like kitchen-living room – can be even very relevant.
• From what power sources the remote works. It is better if they are ordinary batteries, which are available in any store.

Examine the remote control. In good manufacturers it is made of good quality plastic, the buttons “go” softly

Manufacturer

In the Russian market are LED chandeliers for the home born in China, European countries, there are Russian variants. Distinguish them at once – at a price. Chinese – the cheapest, European – the most expensive. Even those whose production is located in China.

Which ones are worth buying? European or proven Russian. They use quality LEDs, which will definitely work out the warranty period. In addition, they support the warranty, that is, repair or replace the failed or changed its parameters of the device.

The whole problem is that outwardly a layman can not distinguish quality LEDs from low-quality. This is revealed in the process of operation – they lose brightness or stop glowing altogether. All hope for control in production, which rejects low-quality LEDs. Inexpensive Chinese chandeliers, most often, are assembled on these discarded LEDs. Predict the duration or quality of their work is impossible. Exception – proven Chinese brands, but the price of their products is not far from European. So… there is essentially no choice.

Another problem of cheap LED chandeliers – low-quality power converter. For quality conversion requires quality (read – expensive) components and professional assembly. All this increases the cost of the device. And not fully “equalized” AC voltage quickly fails even good LEDs, not to mention defective ones.
