LED Strobe lights

LED Strobe lights

Utilizing LED technology as the strobe light source is an innovative approach. It differs from incandescent and compact fluorescent lighting in several ways, while maximizes human response to a light pulse and optimizes light based on parameters of area and perception of the human eye.

LED technology as the light source for strobes can bring significant cost savings. This includes reduction in wire size, fewer power supplies, and less battery standby capacity required for the same coverage area. Competitive models can draw up to 3 times the current. This substantially reduces overall power consumption, allowing for a greater number of appliances on the notification appliance circuit.

But there are other key factors of using LED as a light source for visual signal appliances:

LED light bulbs can last longer and are more durable and offer comparable or better light quality than other types of lighting. Assuming a steady use, LED lights lifespan is between 50,000 to 100,000 hours vs. the xenon strobe with 1,000 to 5,000 hours of life.

The LED light engine can closely control and manage the light source and output. LED technology provides a way to manage this engine and thus optimizes light output. In the other hand, xenon strobes, light can’t be controlled. It is flash only.

Legislation compliance
The National Fire Protection Association (NFPA) updated visual signal light pulse characteristics in the 2016 edition of NFPA 72 National Fire Alarm and Signaling Code. The light pulse duration was reduced from 200 milliseconds (0.2 seconds) to 20 milliseconds (0.02 seconds) in the 2016 edition.
The shorter light pulse requires a much brighter light output to reach the required candela rating. The latest research shows that the brighter light output (the high peak intensity) was found to be more effective at alerting people who were not looking directly at the strobe (indirect viewing).
It also indicates that the peak level of light must be equivalent to a visual signal appliance with a pulse width of 20 ms or less to be used for both direct and indirect applications.

Next Security Corp have a great selection of Life Safety Notification Devices, including the new LED Strobe lights, by Eluxa.

Eluxa’s line is compatible with all fire alarm control panels and accessories, including Wheelock devices and can be installed in the same field of view with xeon strobes.

Tip from experts
Remember that all strobe lights should be synchronized to avoid triggering seizures in people with photosensitive epilepsy.
