Anybody familiar with remote battery emergency lights. My application is one double head per remote battery. Remote head is located outside, wet area. Battery to be right inside of the wall, close to the head.

I'm thinking two heads, common mount, 9W incandesent, 6V, sufficient battery bank for 90 minutes. So far I found Hubble Emergi-lite:
LSM27-2 (Lead Calcium)
LSC25-2 (NiCad)
LSE27-2 (Long life Lead - what ever that is)
all with EF11D remote heads.

Plan is to remove the two heads that come with the battery box, EMT from the battery out to the remote heads. EMT from the battery/charger to the nearest lighting ckt (ahead of the switch)

Questions:
1. What does a NiCad get you over a Lead-Calcium?

2. Does anyone know the difference between Hubble LSE and LSM/LSC series? They don't look much different looking at the cut sheets. Biggest difference I can see is the available battery types.

3. How much light is required at ground level. The EF11 with a 9W bulb is about 1.5fc at 8ft (ground level)

4. If one has two heads, 9W each, photometric data showing 1.5fc at 8ft for one head, does adding the second head double the light - do they add linearly? I'm thinking the answer is, "yes they add." I just don't know if it is linear.

5. Anybody have a recomendation for other brands?

I'll have some answers Monday when I can call Hubble. All I get on the phone now is French speaking voice telling me (I think), "Quebec Office, dial 2", which says, "call after 8AM on Monday"

Why the remote battery? Cause it gets really cold, literally -40F.

I spec Lithonia ELT battery packs without heads and ELA W T IND remote heads. The IND remotes don't give much of a target for vandals with ropes, etc. I'd suggest caution on removing and remoting heads -- it could void the listing, and the heads may not be appropriate for outdoor use. I generally use H1212 (halogen, 12 watt, 12 volt) or H2012 lamps. Smaller wattage lamps don't do much.

hmspe -
Thanks. I'll look at the Lithonia tomorrow.

If I use the Hubble, I'm not remoting the heads that come with the battery pack. I'm removing them from the battery pack, pitching them, and plugging ithe holes. The remote heads would be EF11D. The packs I listed are designed to feed remote heads. According to the salesman (who would certainly know :rolleyes:) is easier to get the packs with the heads than to order without.

According to the EIS the 9W dual heads should give 3fc on the ground. And if it's dark out, I can guarantee the ground is white. One of my questions was what is the minimum light level. I think it is 1fc, but I don't know that yet. If I don't hear from one of us here, I be able to find out on Monday.

Is this something that could work for you

The required lighting is 1 foot candle if I remember corrrectly.

Emergency Lighting and Exit Sign requirements are defined in NFPA101 "Life Safety Code". Emergency lighting is pretty straightforward, it must be arranged to provide initial illumination of not less than an AVERAGE of one foot-candle measured along the path of egress - at floor level. 1 foot-candle is brighter than you may think. There are also limits on the lighting level (i.e. it can't be "to bright") (40 foot candle). The minimum is 0.1 foot candle.

Exit signage requirements are also more detailed than one may think. NFPA 101 also applies.

Those "frog-eye" style emergency lighting fixtures provide enough light for egress in my own personal opinion but I have had difficulty using them to meet Code requirements when I'm asked to provide lighting calculations. They're like spot lights and it always ruins the 40:1 max to min ratio for a corridor or other room.

I usually specify a battery pack like this to use in the general fluorescent light fixtures. Spaced about 30-40 down a corridor. Distance depending on the calculations.
