Are lamp photometrics the same?
Are lamp photometrics the same?
(OP)
Are the photometrics of "let's say" a PAR 36 Sealed Beam 9 Watt Halogen going to be roughly the same regardless of the manufacturer?
I need to have calculations to show that NFPA 101 is being met. I've been using photometric files downloaded from specific suppliers. It seems that each supplier has their own photometrics specific to a particular catalog number. Can I assume as stated above that the calculations will return the same results regardless of who makes the lamp?

Thank you for your reply. The partiular lamps I've been using are not mounted in a fixture, but rather as wall mounted emergency units. I'm trying to find the most cost effective way to meet code. It appears to me that most emergency lighting vendors want to sell you a unit that has a low wattage lamp mounted on it and tell you to buy more units. Well, my calcs indicate that I can simply use less units with higher watt lamp to meet code (common sense). Of course I've run the calcs with carefull placment and aiming of the lamps. I'm using Lite-Pro AND Luxicon software to do the calcs and they are consistant with one another. My main question (which I believe you answered), is, for instance: Is a 10 Watt PAR 36 Sealed Beam lamp VERY consistant in photometrics, regardless of the manufacturer? Thanks
