Replacing halogen spotlights with LEDs. Features of choosing a r7s LED lamp

Today, consumers are setting increasingly stringent and demanding criteria for assessing the quality of lighting. Because of this, the development of lighting fixtures and light sources does not stand still, but is constantly progressing and trying to meet the needs and whims of customers.

LED technologies stand out with a special pace of development, which are developing at a staggering speed and are far ahead of progress. In this article, we will tell you about the variety of LED lamps with r7s base, how it works and the scope of such a device.

Working principle and scope

Such lamps are preferably used on the scale of small rooms, for installation in portable spotlights 118 or wall-mounted street lamps. Due to the unusual structure of the base, the use of such devices at home is extremely rare, since a special lamp should be prepared for them.

Widespread in household, industrial and commercial areas, in small-sized spotlights.

Due to the unusual structure of the r7s base, such lamps can be considered specialized and intended for use only in certain conditions with special devices. Due to the low level of electrical energy consumption, they are ideal for 118 floodlights, and are most often found in their design.

Such a LED lamp works on the same principle as any other LED device. In the middle of the whole circuit is a semiconductor, which is connected to the anode and cathode, which direct current to it, as a result of which it begins to emit a stream of light.

In connection with big power lamps, R7s cartridges are always made of ceramic, and a piece of heat-resistant wire is permanently attached to the spring contact.

In order to ensure the quality of the light that we receive from the LED, the current is supplied to it through a rectifier, which is simultaneously connected to a special board or, as it is also called, a driver. It is with the help of a driver and a rectifier that the LED is able to provide the highest quality of the emitted light.

Varieties of lamps with r7s base

Since such lamps are used in various spotlights 118, but their shape will also be slightly different, in general it remains unchanged, only the size changes. For small spotlights, the lamp will have a more knocked down and compact shape, and large spotlights are equipped with oblong and elongated barrel-shaped light sources.

There are models protected in a glass flask, and they are not afraid of mechanical and atmospheric effects.

Since the r7s base implies the connection of the lamp with two contacts, which are located on opposite sides in the spotlight circuit, manufacturers do not produce them in shapes other than barrel-shaped.

Corn-shaped model, compact, unprotected

LEDs in the design use a wide variety, but in most cases they differ in their power. In general, all LEDs that are installed in such lamps can consume from four watts, which is certainly incredibly small in comparison with any analogues.

Also, the angle of illumination that the light source can give out will also depend on the location of these LEDs, often it is in the range from one hundred and eighty to two hundred degrees.

Choosing the right device

When buying, everyone wants to get a quality device that will fully meet all the requirements so that the money spent is not simply thrown away. So you should not be guided only by the recommendations of the sales assistant in the store, very often they are not particularly knowledgeable and know the exact criteria that should be emphasized.

When choosing a lamp, pay special attention to the shape and distance between the socles.

It's best to get your own knowledge base and go to the store armed with an understanding and the exact performance you want from each light bulb you buy. So, what should you pay priority attention to:

Lamp power

Of course, the very first and most important criterion is the power of the selected device. Its indicator should be selected very carefully based on the area of ​​\u200b\u200bthe room or street that will be illuminated with it.

Table of efficiency and light output various types light bulbs

You also need to take into account the illumination value that you want to get. Remember, this parameter will directly affect the cost of electrical energy, so choosing the right one will save you both on the bulb itself with the r7s base and on the energy costs for its operation.

Degree of protection

The degree of protection of the light source. For use in open space, where moisture, dust, wind, sun, etc. will get on the lamp, this indicator should be as high as possible.

IP protection table

In this case, you will be completely sure that the light source will not be damaged and will not fail at the most inopportune moment.

Beam Angle

Angle of light emission. It should be just as strictly the way you need it. Since lamps with a large angle will cost more, and not every spotlight is able to provide an angle of illumination, for example, two hundred degrees. Thus, by installing in a small spotlight with a diameter of 118mm, you will be wasting excess emitted light.

The distance between the contacts on the lamp

R7s lamp length dimensions

Correspondence between the contacts on the lamp and in the spotlight. This is very important, because in the case when you buy a light source that is too large, it simply will not fit into your spotlight and will be useless, but if you buy a short bulb for a 118 spotlight, then the situation may be the opposite, the contacts will be missing and connect it to device will not work.

As you can see, there are not very many criteria, but now you know exactly what you will need to pay priority attention to, and you definitely won’t go wrong with the quality and compatibility of the device you buy. Go boldly to a specialty store and buy exactly what you need to light up any dark corner of your room.

We select a manufacturer

Many people are wondering which manufacturer should be chosen, which of them is worthy of standing in a number of leaders and being the first in terms of LED lighting. Some argue that expensive brands win significantly in quality, others say that cheap ones can compete with flagships, who should be trusted? We will help you understand this difficult issue, the confrontation between expensive brands and cheaper and, accordingly, affordable analogues.

To answer this question, you should decide for yourself exactly why you are chasing to get maximum quality or you just need to somehow illuminate the area within the allowable limits. If you want to get the most out of your purchase, then, of course, you should choose a light source for a 118mm spotlight from more expensive models.

Brand manufacturers use high-quality and reliable LEDs in their devices, which, even after a long service life, remain the same quality, and the emitted light practically does not deteriorate.

When buying cheap analogues, be prepared that over time the quality of light will gradually deteriorate, and by the end of its service life it may become completely bad and absolutely unacceptable for use.

This is due to the fact that manufacturers are trying to make the design as cheap as possible and install lower quality and at the same time cheap elements, which significantly affects the performance.

As for the cost, it varies depending on the design features and, of course, the power of the LED light bulb with the r7s base for the spotlight 118. The starting price of one device, for example, five watts, will be about six dollars. A light bulb with an r7s base for a 118 x 7 watt spotlight will cost you ten dollars already.

I had an old 500W halogen light in my garage. I used it to illuminate the underside of the car from the viewing hole. Very convenient good lamp with the handle and a protective lattice. But here's the problem: the halogen lamp burned out. Of course, such lamps are still on sale today, but I decided to upgrade the lamp to make it more economical, brighter and more durable.

Not so long ago, LED matrices with built-in drivers began to appear on the Chinese market right on the body of the matrix itself. This driver is designed for an alternating voltage of 220 V. In a nutshell, this is just an LED that is powered directly from mains voltage without additional boxes and accessories.

And the main advantage is low price – .

The purchase cost less than 150 rubles. I took a 50 W LED matrix and a voltage of 220 V, which I actually needed. The brightness of such an LED is quite comparable to a 500W halogen lamp.

Converting a lamp to LED

I used this redesigned spotlight for over a month. In principle, there are no disadvantages, only advantages. Especially the savings in rubles for electricity per person.

In our online store you can find buy lamps with the following color temperature:

warm white light 2700-3000 k;

neutral (natural) white light 4000-4200 k;

office/cold white light 6000-6500 k.

The light spectrum of the lamp should be selected based on the location of the spotlight. For indoors, you can purchase a lamp with a warm white or neutral glow, but for the street, cold white light is more preferable, since it is the brightest and will provide good

Modern manufacturers of lighting equipment apply more and more new technologies in order to offer their customers the highest quality products. Searchlights belong to the class of waterproof lighting equipment, which is actively used for installation in production shops, warehouses and utility rooms, entrances of apartment buildings, as well as for street lighting - in car parks, adjacent territories, in parks, squares, etc. Due to the durable metal body, the spotlights perfectly withstand temperature fluctuations and harsh weather conditions - such lighting will perfectly "feel" in damp rooms with a high level of humidity and in unheated rooms where full lighting is required.

When choosing a suitable lamp for a spotlight, pay attention to its power and the correspondence of the base of the lighting element to the base of the spotlight itself. The catalog of our online store contains LED and fluorescent lamps, which can be selected for any model of spotlight. Most of all, LED lighting elements are preferred because they have an energy-saving effect and, even with active use, will allow you to save on utility bills for electricity. In addition, LED matrices do not contain mercury substances, therefore they are considered a safe and environmentally friendly light source, which is especially important when arranging residential premises.

All presented models are quite easy to install and replacement of a lamp for spotlights of street lighting of a building fits most cartridges used in modern models searchlights.

We are talking about replacing one of the varieties of halogen bulbs (popularly called thermometers) used in spotlights with an LED counterpart. Of the infinite number of products on the site, this one has not been previously reviewed. I will try to make up for this shortcoming.
Replacing halogen lamps in a spotlight, there is also this: I will talk about fashionable LED counterparts. I have been successfully using one such copy since last year. Having recently found fittings (the spotlight itself), I bought more. Initially, a spotlight with a 150 W light bulb looked like this:

Those who have similar ones know that “thermometer” lamps often burn out, because there were quite a few of them. The difficulty is created not so much by the lamp itself, but by replacing it. For it requires the installation of a ladder and disassembly-assembly of the body, and the weather can be different ... Therefore, such a reserve has accumulated:
Chose to replace led light bulbs 78mm 5W, warm spectrum, non-adjustable driver, with 24 5730 LEDs. Cost me $4.90 each, C large quantity I did not take LEDs, because the brightness does not increase significantly, and the likelihood of overheating increases. However, this opinion is private and subjective.



Bulbs of this type are relatively expensive, but made with high quality. I unscrewed two screws each and removed the side walls, presenting the insides according to tradition. Wires do not allow to get completely. The transformer and electrolytic capacitor are clearly visible. Base, aluminum profile frame, plastic walls on the side with contact and slots for ventilation, inside the circuit is in a film, the wires are all silicone. Boards with diodes are cooled against an aluminum frame.


Of course, the light output of a halogen lamp cannot be compared! At the same time, a 30-fold difference in illumination, as well as in power consumption, is also not observed. My LED spotlight successfully illuminates an area of ​​about 4 meters in front of me from a 2.5 meter height. In this case, the role of the reflector is more aesthetics. The light, who knows, from LEDs is specific, but this is quite enough for me!



Separately, I note that the advantage of such a modernization of the spotlight is:
- a significant reduction in electricity consumption (now it is becoming relevant)
- durability
- the safety of the searchlight glass, cases of their cracking from heat are not uncommon
- constancy of brightness, regardless of the voltage in the network (85-265 V). When used with a motion sensor, do not use such lamps! They will flash from time to time. Choose similar ones, but with a dimer. They will not have such a disadvantage, but cost a little more.
There is also a replacement for larger halogens: 500 W - 118 mm and 1 kW - 187 mm
There is only one drawback: the replacement is not equivalent in brightness. But it is not rare that LED lighting will be enough.
Unfortunately, I do not have the opportunity to measure the true power consumption and luminous flux.
The seller sent the goods on the second day. Delivery was China Post less than 2 weeks. Now it is difficult to surprise with such terms ...
Thank you for your attention!
