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.
