What protections for outdoor luminaries

What protections for outdoor luminaires

outdoor light


Installing outdoor lighting is a bright idea, but be sure that the chosen lamp is well suited to where it is placed and the use you want to make.

For clarity here is a small guide to the meanings of IP protection standards.

 What does IP protection mean?
On all lamps which are intended to be used outdoors, there is a protection index that is standard and established at the international level by the international electronic commission. This index is identified by two letters "IP" and two numbers that are variable. IP protection ratings are intended to classify electrical equipment according to resistance to the intrusion of foreign bodies whether liquid or solid.

 The two letters "IP" are therefore followed by two digits, the first varies from 0 to 6 and determines the resistance of the product to the intrusion of a solid body, the second varies from 0 to 9k and defines the resistance of the same material at the intrusion of a liquid body (often water.).

Here are the different types of protection indices most common:

-        IP20: the 2 means that the luminaire is protected against solid body intrusion of a size greater than 12mm and  0  that it has no protection against splashing water. It is strictly reserved for use inside the house.

-        IP44: the first 4 indicates that the product is protected against the intrusion of a solid body of more than 1mm and the second 4 that no projection of water from all directions can enter inside. It is possible to use this luminaire outdoors without a security problem.

-        IP65: the 6 shows that the protection of the luminaire is total even facing the dust and the 5 that it can withstand the projection of water from all directions with force.

These three indices of protection are the most common but you should know that all combinations are possible and that the lights that are placed in the pool or the bright balls that are placed on the water are classified  IPX7.X because it is a material that does not fear any intrusion of a solid body and  7 because it resists the intrusion of water up to 1m deep.


These IP ratings are for electrical equipment such as outdoor fixtures and outlets, but it also works for electronics such as the latest waterproof and dustproof smartphones.

Why switch to LED?

Why switch to LED? Accessible for all budgets and economic? The LED is no longer this standard bulb, ecological but without charm and a little too expensive. Today, LED has revised prices down and comes in several models. To finally switch to LED, here are our top 5 advantages of an LED: 1 - LED consumes very little energy LED technology consumes 10 times less than an incandescent bulb, 6 times less than a halogen bulb and even less than a compact fluorescent bulb, already known to consume little. This low energy consumption makes the LED an eco-friendly bulb to be favored to preserve the environment. 2 - LED is economical LED, in addition to consuming little energy, is sustainable since it can last up to 50 000 hours is 50 times longer than a conventional light bulb. LEDs can, therefore, save energy but also financially because it does not need to be changed regularly. 3 - LED is recyclable Unlike incandescent bulbs, LED bulbs are recyclable and above a...

Look on the butts!

Look on the butts! The base is the metal part of the lamp that allows it to be fixed in a luminaire. There are so many different tips that it is important to know how to differentiate them and to know their usefulness. Here is a small reminder of most of those existing: Screw caps The E27, the standard size Let's start with the most common which is the E27 screw cap. It is the most used every day in our homes. The E27 is 27mm in diameter and is the standard size compatible with most fixtures. The E14, the smallest The smaller E14 is 14mm in diameter and is appreciated for its elegance and subtle appearance. Bayonet caps In our Anglo-Saxon friends, like screw caps in our home, the bayonet caps with pins on the side are the most used. A  B22 is a base of 22 mm in diameter. GU for spots The GU is for spotlights and ceiling décor and some equipment. The GU10 cap is the most important in its size. Indeed, its two pins are separated by 10 mm. Th...
