LEDs are the most popular and economical lighting products that are widely used in domestic and industrial conditions. We offer you to consider how to choose LED lamps for spotlights, where to buy them and what is their cost.
When buying light bulbs, we are used to evaluating W, a brightness or power indicator, with LED lamps everything is different. The definition of power and light output determines differently.
Contrary to popular belief, power is not an indicator of brightness, but an indicator of how much energy a lamp consumes. For incandescent lamps, there is a generally accepted correlation between W and brightness, but for LEDs, W is not the main indicator.
For example, LED lamps with a comparable brightness of a 60-watt incandescent lamp have a power of 8 to 12 watts. For example, to replace 35W halogen lamps, diode models of 16 W or 12 W will be used, this may be the products of MR, Lion, Lux and others. Although, according to the standards in Teplosvet you can use three-watt devices.
In connection with the difference of these indicators, a unit was invented - lumen, which determines the ratio of power to light brightness. The photo shows an approximate diagram by which you can choose the power of LED lamps. For example, a 12 V lamp connected to a 220 V network will produce a brightness of more than 1100 Lm.

Variety of shades
Incandescent lamps can provide only yellow or very warm, milky light. Because of this, its quality and brightness significantly decreases.
LED lamps are capable of displaying an impressive range of colors, from purple to red, a spectrum of white and yellow. If desired, you can choose a model that will match the color of incandescent lamps as much as possible.
Before buying bulbs, be sure to check the color scheme, on the packaging it is presented in Kelvin. The lower the number, the warmer the light. The usual shade of incandescent lamps is in the period of 2700 and 3000 Kelvin. The higher the indicator, the brighter and colder the light will be.
Sharp colors negatively affect the eyes, so we recommend using them either in case of emergency, or for installation on billboards or in exhibition halls.
Power consumption
The main characteristics of LED lamps are energy consumption and durability. As you know, LEDs are an order of magnitude more expensive than incandescent lamps, but along with this, they shine much brighter, last longer, and consume several tens of times less power than ordinary fixtures.
Spotlights with LED lamps work up to 8000 hours, with infrequent on-off light this figure increases. It also increases if there are no voltage drops in the network. The location of the device significantly affects performance - any devices can be used in the house, but install only special street lights in the open air.
Installation
It is very important to choose a model with the appropriate cartridge. There are several ways to install lamps in fixtures:
- Cartridge (the most common);
- Insert directly into the lamp housing on the contacts;
If the bulb is bought separately from the lamp, then you need to clearly know the size of the cartridge. The spotlight lamp is very similar to a conventional incandescent model, with the exception of size and principle of operation.
It is most convenient to mount lamps with an mp-16 gu5 base - they are easily installed and used in 80% of LED spotlights.
Tightness
Spotlights are leakproof and open. The first should be used in bathrooms, saunas, and other places with high humidity, for these rooms we recommend choosing a model with a stainless base and a durable glass that will not burst under the influence of steam and drops temperatures. Non-sealed can be used absolutely everywhere, except for rooms with high humidity or open rooms.
It should be noted that decorative spotlights cannot be used in production conditions and in explosion and fire hazard zones.
