Despite its many strengths, it is necessary to handle the halogen bulb carefully. So she will give you full satisfaction
Halogen bulb gives off heat
Because of its design, Halogen gives off heat. Indeed, a halogen bulb consists of a tungsten filament protected by a quartz glass filled with halogenated gas under pressure. Worn at high temperature, the tungsten filament gives a radiant light. But, it heats! And even more so than traditional incandescent bulbs. All you have to do is bring your hand near a light bulb that is working to feel this strong heat.
It must therefore be placed in a place where it will not be not in contact with flammable materials like curtains or curtains, for example.
And beware of the little exploratory hands of young children.
Similarly, avoid confined areas. This is all the more important if you have halogen spotlights built into a false ceiling. Always ensure that heat can escape.
Does the halogen bulb present a danger to the skin?
When halogen became popular in the early 1990s, there was controversy over its dangerousness to the skin in direct exposure to halogen light. The question, of course, does not arise for luminaires with indirect lighting. On the other hand, the questioning is all the more relevant because many office lamps and workplace lighting have a halogen bulb. Indeed, this type of bulb emits ultraviolet radiation (UV).
These are the famous UV that give us a nice tan in the summer but can also burn (no less famous sunburn) and be dangerous for the skin in the long term. Manufacturers have taken these potential risks into account and today almost all of these bulbs have a filter or a double jacket. Otherwise, it is the luminaire itself that has protection.
The question may also arise for the risks concerning the retina. But because of its high light intensity, if you look directly at a halogen bulb, automatically you will blink and look away.
Can a halogen bulb explode?
This risk exists in fact with almost all bulbs. Fortunately, it's very rare. Nevertheless, it is necessary to emphasize a fragility inherent in the design of the halogen bulb. The glass used to contain the tungsten filament and the gases under pressure is a quartz made of amorphous silica.
The deposit of a fatty substance (skin of the fingers that touch the bulb, insects that land on it) contaminates the surface of this glass and by chemical reaction weakens it. That is why, it is not recommended to touch directly with your fingers a halogen bulb which is not protected by a double envelope. If you have nevertheless grasped your halogen bulb by hand, do not panic! Clean it gently with a rag soaked in alcohol. This will eliminate any trace of your indelicacy.
