Emergency Lighting Query

[wallyanker]

Hello

Our warehouse manager informed me today that during a 2 minute power cut, the emergency lighting came on and then went off again when the power was restored. I couldnt see the problem until he explained that the big bay lights used to illuminate the picking isles did not come back on for approx 10 mins (400w-600w sodiums I believe). So his staff were stood in the dark waiting for the lights to come back on. :dizzy2:

Can you install any form of time lag switch to the emergency lighting so that when the power is restored, they still continue to work for 10 mins or so?? Picture below is the type of emergency lighting installed in the warehouse.

Thanks

there are fittings with a GLS lamp beside the normal discharge lamp for such times I cant find make right now but I have used them in a warehouse they arent meant to provide enough to work by but to provide illumination while the main lighting reignites for safe movement
