At GreenIce we want more people to be able to enjoy the savings they get in every home and business with LED lighting.

Facilities at very low safety voltage (MBTS)

Installations at very low safety voltage include those whose nominal voltage does not exceed 50 VAC. Or 75 VDC, powered by a protective insulation source, such as a transformer that complies with current safety standards.
Within this type of facilities, we can find:
- Sanitary automation
- Pools Spotlights
- Automatic floats in pumping tanks
Irrigation of green spaces
- Hydro Massages
Outdoor Lighting
 If we work in dry, humid or partially humid outdoor environments, such as outdoor floodlights, the recommended voltage is 24 volts. On the other hand, for elements that are going to be submerged, like pool bulbs, the recommended working voltage is 12 volts. For both purposes, a safety transformer must always be used with the appropriate protections.

Importance of the beam angle

The beam angle indicates how much the light beam will open when you exit the lamp, that is to say, under the lamp will create an illuminated area whose area is proportional to the opening angle. To select the proper lamp, this value is of vital importance because it would directly affect the uniformity of the light, and the number of luminaires to be used.
Therefore, it must have a balance between the proper medium illumination and the uniformity of the light, always ensuring that the whole place is illuminated and without shadows.

Advantages of LED Technology

If you still have you have not gone to the LED lighting and you have in your home incandescent or halogen bulbs, GreenIce gives you the reasons to make the transition to the lighting of the future.
Energy saving
Today, energy saving is one of the basic pillars of any person, because in this way it contributes to make a transition towards greener and more efficient technologies. LED technology is the most efficient lighting form, (80% less compared to traditional lighting). This means that about 80% of the electrical energy becomes light, consuming very little power and, therefore, emitting very little heat. Traditional incandescent bulbs only convert 20% of the energy into light, losing 80% in the form of heat.
Durability
LED lighting is characterized by the long life span it possesses. Its half-life is around 50,000 hours. The duration of these is not calculated according to the time when they are switched off, but based on a percentage of the initial luminous flux (lumens). This means that the LED luminaires continue to operate once the specified service life hours have been consumed, although with less intensity. In addition, due to its great useful life, it makes maintenance costs less than for traditional technologies.
Environment
LED devices do not contain mercury, do not produce infrared irradiation, do not produce light pollution and are 100% recyclable. All bulbs and luminaires in the GreenIce catalogue have the RoHS certificate (Restriction of hazardous substances), which prohibits the use of six materials in the manufacture of electrical and electronic equipment.
The long operating life period mentioned Previously It means that a LED light bulb can save material and produce 20 incandescent bulbs.
In addition, the use of LED lighting technology makes the carbon footprint and CO2 and Sulphur emissions decrease in the atmosphere.
Quick response Capability
Unlike traditional technologies, the LED lighting has a very fast start, so it does not need a preheating before (such as fluorescent tubes).
Mechanical resistance
Unlike traditional light bulbs and luminaires, the LED lighting has a high mechanical strength so what can withstand vibrations and blows, which makes the transport better support the blows without any damage. In them.
Chromatic variety
The LED Lighting offers a wide range of chromatic variety with which one can choose different intensities of light, effects and environments depending on the lamp or luminaire chosen. In addition, there is the option of RGB (red, green and blue, in its acronym in English) in which one can choose between the three shades base and the tonalities that are obtained from the mixture of the three (yellow, purple, pink, white, etc.). In addition, the LED illumination has a CRI (chromatic reproduction index) greater than or equal to 80. This parameter indicates how much fidelity the LED illumination plays, so the closer it is to 100, the greater the color reproduction fidelity.

How important is the luminous flux?

With the introduction of LED technology in the lighting field, new very important concepts have been introduced when choosing the right bulb for our purpose. With traditional light bulbs, the factor to take into account when choosing a bulb was the power (W). At present, this factor is no longer so important, with other factors such as Lumen (Lm) and luxes (Lx) coming into play.
We will then explain the difference between the two, as well as some examples that will help us better understand these new concepts.
Lumen: It is the unit of the international system to measure the luminous flux of a source, that is to say, the luminous power that provides that source.
To set an example, a 60w incandescent bulb with E27 sleeve has between 600 lumens, being the replacement to LED by a 8w bulb, with the same number of lumens and therefore the same level of illumination.
Example of luminous intensity.
Lux: It is the unit derived from the international system for illumination or lighting level. Your unit is Lumen/m2. With this parameter you can know how far reaches the beam of the light source and how good or bad is the lighting that is in each place.
The Une 12464-1 standard is the European standard on indoor lighting. The average illuminance levels are tabulated in this standard (E)m), the rates of unified dazzling UGR (UGRL) and color performance indexes or chromatic reproduction rate.

How to select the right color temperature?

Warm White (3000 - 3500 K): Yellowish Color. The shades of warm white are usually chosen in rooms where tranquility and relaxation are required. These rooms are bedrooms, lounges, dining rooms, hallways, etc.
Natural White (4000 - 4500): Pure white Color. The shades of natural white are usually installed in places where an optimum appreciation of the colors is required. These rooms are bathroom and dressing room.
Cold White (6000 - 6500 K): Bluish white. Cold white shades are usually installed in places where lighting is a very important factor and manual and precision work is performed. The rooms are from kitchens to workbenches.

Importance of opening angles in lighting

One of the most important factors when choosing an LED bulb is the opening angle. The smaller the opening angle, the more focused the light will be, while, if we choose a very open opening angle, the light provided by this product will be more dispersed, although it covers more lighting distance. Thanks to the constant development of LED technology, we can find products with different opening angles, being able some of them to illuminate an entire stay.
The most commonly used opening angle is the 120 & °, as it is usually found in most places in a home. When we want to focus a particular point, the angle we will have to choose is 40°.
It should be taken into account, that the higher the height to which the luminaire is placed, the lower the angle of opening must be for the illumination to be correct and 100% the luminous power provided by the product can be exploited.

Differences between single-phase, two-phase and three-phase rail bulbs

Within the installations of rail bulbs, there are three types of configurations according to the ignition points or phases that we have or want to put inside our installation. The types that exist are the following.
- Single: Single-phase rails and spotlights are used when inside our installation we want one point of on/off. This type of facility is the most common and the most used.
- Biphasic: Biphasic bulbs and rails are used when inside our installation we want two well differentiated on/off points. For example, if it is along a hallway, you can put a switch at the start of it to perform the general ignition and another switch at the end of this to make the total pay.
- Phase: 3-phase rails and light bulbs are used when inside our installation we want three on/off points. This type of configuration can be used in installations where you want to perform specific installations and/or parcels.

Differences between motion sensor and presence sensor

Presence sensors are more sensitive than motion detectors as they collect the slightest movement. This is because they have more sensitive sensors that perform a constant sweep in up to 1000 zones. Moreover, another notable difference between the two is that the presence detectors perform a constant measurement of the illumination levels, while the motion sensors only perform a Time.

Differences between infrared (IR) and radiofrequency (RF)

All products that work through Infrared They work by emitting pulse of light with a wavelength between the ranges of infrared radiation, while radiofrequency is based on the emission of radio waves. Both Technologies work in the same way as those with the greatest reach of radio frequencies as they are able to traverse walls.
