When i changed two tubes in two emergency lights ( the ones with the green man ) the lights stays on continuously. Please help. Is the units faulty ?

Sounds like they are "maintained" emergency lights. Maintained emergency lights are lit all the time.

As green-foam has said is sounds like a maintained emergency light but is it required please describe the premises and its function.

Yep will be maintained exit boxes - my guess is that you are a restaurant or similar?

I have  a  Ventilux emergency light in the corridor of my  apartment. For the  past few weeks, it has been staying on most of the time, especially at night. It is 'Self-Contained without Rest Mode'. I don't know why, but is it likely to remain on if the battery is depleted or is there a battery in this unit. I have not done anything to it since I moved into the apartment in 2005. Thanks.

Which model is it?

I have emergency light in room and its staying on after power is back

Sounds like they are "maintained" emergency lights, maintained emergency lights are lit all the time because certain situations require it or it could be a fault, it may be worth getting a specialist to check it out.

 

Hi, my emergency lights in the pub just switched on however I still have electric everywhere. I checked the fuse boxes, alarm. Everything seems to work , I don't understand why my emergency lights are switching on. 

Assuming they have always normally been off it would suggest something affecting the supply to the fitting between the consumer unit and the fitting (wiring, junction boxes) or a fault in the unit.

When it's lit does the little red or green LED light on it go out?

I have a non-maintained emergency light fitting that gradually illuminates when power is on (green light on)  It gets up to half brightness and stays like that. When power is removed, full brightness comes on. Seems similar to previous postings. Any ideas?

There appears to be a problem with the electronics of the light fitting. It would be cheaper and quicker to replace the light fitting than to take it down and then to find someone to diagnose what component has failed (Capacitor)

Hi, replaced an emergency light in my loft. Different type. LED. LN E.and plugged battery connection. Renewed the supply...light is on??? Thought it would be off, until I have power failure. Manual sheet is useless.

There are generally two types of Emergency Light. Maintained and Non Maintained.

Maintained has a permanent mains supply, its light source is illuminated all the time.

Non Maintained has a permanent mains supply but will only illuminate when the device has a power failure.

Some non maintained Emergency lights can be configured as maintained. You may have purchased a Maintained light instead of non maintained light, or you may have configured it wrong.
