Talk:Emergency light

Why no mention of emergency lights using fluorescent tubes? Bruern Crossing (talk) 12:19, 30 March 2009 (UTC)

Some Additional Information

There are new models of Emergency Lighting called "self contained, self maintained" emergency lighting.

For these lighting equipment, they usually perform like normal fluorescent lamps in normal condition. When the AC power is failure, these lamps will automatically switch to battery powered supply, with lumen intensity around 20 - 30% of normal brigthness. Safety regulations of most European countries requires lighting contractors to provide certain percentage of such lamps in their lighting projects, especially in public areas, like underground, hospital, school, etc.

Since each self contained emergency lamp is an independent system, you will have more standby lighting sources in same area compare to traditional system. It will be more reliable (and more expensive).

LED Emergency Lamps are more commonly used receently. It allows to use smaller battery pack with cheaper cost and more compact size, but its key component - inverter, are different.

Batteries requirement for such lighting equipment are very high. Instead of Lead Acid batteries, manufacturers normally use High Temp Nickel Cadminium dry rechargeable batteries for more reliable and more compact reasons.

Cadminium? Never heard of that.

Reliable battery is very important for such system. Since the market demand is not big, many battery manufacturers don't pay much attentions in such products and you have to be very careful. Suppliers includes Saft in France, Sanyo in Japan and Sanforce in Hong Kong, of course, there are so many other good suppliers. You need to test for at least 50 cycles to ensure its quality. —Preceding unsigned comment added by Stephen Kwok (talk • contribs) 03:32, 2 September 2009 (UTC) Sanforce in Hong Kong are now bought and operated by Tracino Eco Ltd, with further development of battery and inverters. — Preceding unsigned comment added by 210.177.225.145 (talk) 05:53, 4 August 2016 (UTC)

Needs to be globalised

This article does not mention the international standards for emergency lighting nor the use of selfcontained emergency fluorescent lumenaires. It appears to be base on US practice.

Adverts?

Why are there external links to two emergency lighting suppliers? Are such (unreferenced) adverts allowed on Wikipedia? —Preceding unsigned comment added by 212.57.243.14 (talk) 12:32, 3 May 2011 (UTC)

Disney Princesses?

I think the edit that was made today is vandalism. At least to me it is incomprehensible what Disney princesses would have to do with this topic. 83.134.7.166 (talk) 22:08, 11 November 2023 (UTC)

Indeed it was a vandalism. I've reverted it. זור987 (talk) 08:55, 12 November 2023 (UTC)
