LED Emergency Light Kit

em kit

I saw a very similar discrete emergency light fitting recently and thought that would be a good idea over the stairs at home, looking on eBay I saw the above unit (MJ-LED-DZ09 by Zenergy) for £14.95 and bought one.

Prior to use, the instructions recommend charging the battery for no less than 24 hours before use as it comes discharged, this I did.

The LED light housing is really neat, it requires a 32mm hole (1 1/4″) drilling to accept the light body which is held in the hole by spring clips on either side, the electronics are in a low profile enclosure and this will easily pass through the 32mm hole.

Installation was very simple, I marked the center of the ceiling over the stairs, using a 32mm hole saw, checking that their wasn’t any joists or obstructions in the loft  above the ceiling before drilling.

To stop plasterboard dust going everywhere whilst drilling the hole, I used a plastic fast food container as a ‘dust catcher’.

To make this, I cut a hole in the container so that the hole saw shaft passed through the container into the chuck, this allowed me to hold the container steady whilst drilling the hole at slow speed so that all the dust was trapped in the container.

After pushing the electronics enclosure through the hole, I used decorators caulk around the inside lip of the LED light, before pushing the light into the hole, the reason for the caulk was to form a decent seal to stop any draft marks appearing around the fitting at a later date.

In the loft, I connected the emergency light 230v power to the upstairs lighting circuit (after isolating the supply!), when the power was turned on, the battery was then plugged into the unit ready for testing.

With the power on, a tiny green healthy LED is lit, when the power is off, the green LED goes out straight away, and within 2 seconds, the main white escape LED lights, I assume the delay is to avoid and short duration blips bringing on the main LED.

The light from the unit is very bright and cool white is colour.

NO.:MJ-LED-DZ09

Application:

The series use for emergency lighting. The unit will provide 3W maximum output power at emergency mode.They are designed to be highly efficient and highly reliable, and with short-circuit protection; overcharge protection;over discharge protection and over temperature protection.

Important information for the installion:

The unit uses dangerous mains voltage,(220-240Vac, the converter will be with the emergency mode when the mains voltage is less than 65% of rated voltage) it should be installed by a qualified electricians only according to European safety standard or relevant nation regulations.

Connect the LED spotlight to the emergency LED converter with correct polarity according to the schematic drawing.

Connect the unit to AC power only after the wiring completed between emergency converter, battery and spotlight.

If the emergency converter is used for purposes other than originally intended or it is connected in the wrong way, no liability can be taken over for possible damages.

 Specifications:

Model Main power supply Main power cut off
MJ-LED-DZ09 LED Spotlight off, green indicator on LED spotlight on, green indicator off

I’m really impressed with the product, and its another safety related home improvement which we hope is never needed in anger.

Update 6 June 18

Installed a Emergency light test switch rather than turning the lighting power off, these are just under £3.00 and include the ‘fish tail’ key.

Em Switch

The switched fused connection unit is for a cupboard light and Hive light fitting which are fed with 0.75mm cable, the emergency lighting is fed with 1.5mm cable and is not fed from the fused side of the fused connection unit.

One thought on “LED Emergency Light Kit”

  1. Thanks for sharing this. I would like to add few to your list.

    1. Ecologically Friendly – LED Lighting Is Much More Eco-Friendly
    LED lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of materials like e.g mercury that are dangerous for the environment.

    LED lights contain no toxic materials and are 100% recyclable, and will help you to reduce your carbon footprint by up to a third. The long operational life time span mentioned above means also that one LED light bulb can save material and production of 25 incandescent light bulbs. A big step towards a greener future!

    2. Durable Quality – LED Illumination Can Withstand Rough Conditions
    LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.

    Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure and construction or manufacturing sites.

    3. Zero UV Emissions – LED Lighting Features Close to No UV Emissions
    LED illumination produces little infrared light and close to no UV emissions.

    Because of this, LED lighting is highly suitable not only for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, but also for illumination of UV sensitive objects or materials such a in museums, art galleries, archeological sites etc.

    4. Operational in Extremely Cold or Hot Temperatures
    LED are ideal for operation under cold and low outdoor temperature settings. For fluorescent lamps, low temperatures may affect operation and present a challenge, but LED illumination operates well also in cold settings, such as for outdoor winter settings, freezer rooms etc.

    5. Low-Voltage – LED Lighting Can Run on Low-Voltage Power Supply
    A low-voltage power supply is sufficient for LED illumination. This makes it easy to use LED lighting also in outdoor settings, by connecting an external solar-energy source and is a big advantage when it comes to using LED technology in remote or rural areas.
