Common LED Questions

Can LED light bulbs be used in enclosed fixtures?

Because LED bulbs are still a new technology to many people there’s often some confusion about where they can be used. For example, can LED light bulbs be used in enclosed fixtures? Let’s answer that common question…

So, can LED light bulbs be used in enclosed fixtures?

While you are absolutely free to put an LED light bulb into an enclosed fixture most LEDs are not best suited to this.

An enclosed fixture light fitting might be found in bathrooms or kitchens to keep moisture out. Or outdoors to protect the bulb or circuitry from rain and bad weather. The fitting will be sealed so there is no air flow around the bulb.

A normal LED light bulb will still work in an enclosed fixture but its lifespan will be shortened and it will start to lose brightness quicker. In practice, LEDs work better with air flow around the bulb.

It’s a heat issue – so while LEDs only give out a tiny fraction of the heat of traditional bulbs, in an enclosed fixture there’s nowhere for that heat to go. Traditional bulbs used in enclosed fixtures had to have special circuitry adjustments to make sure they didn’t overheat and explode.

An LED won’t explode, but it won’t be as efficient as usual. You can get specialist LED light bulbs for enclosed fittings though. These bulbs will regulate the current so as to regulate the heat.

LED light bulbs will work in enclosed fittings but unless they are a specially-designed type they won’t be as efficient as they should be. Or you can get whole light fittings designed to work with LED bulbs. They will be enclosed but still give the bulb optimum conditions.
