Re: What LA \'s can I run in the Surefire TurboHeads?
There are five major SureFire TurboHeads:
"T" 3" diameter Lexan
"12PM" 2.5" diameter Lexan
"SRTH" 2.5" diameter Lexan [without threaded bezel rim]
"KT" 2.5" diameter Pyrex
"Millennium TurboHead" 2.5" diameter Pyrex (Shock Isolated, only in HA)
Lamp Assemblies:
N1 - two SF123As (6PT or C2+KT1)
N2 - three SF123As (9PT or C3+KT2)
N3 - 9AN+KT3 or 9NT [T3]
N4 - 6RT or 7Z [T4] (Also fits the G2R+TurboHead)
N5 - 8AX+KT5, 8NX+KT5 or 8XT [T5]
N62 - four SF123As (12PM/12ZM/Leopard)
MN15/MN16 - three SF123As (M3T/M9x0AB/M5xxAB/M97)
MN60/MN61 - four SF123As (M4/M98)
MN20/MN21 - six SF123As (M6/M5xxB)
The T1/T2/T4/T5 use the same T TurboHead.
The KT1/KT2/KT5 use the same KT TurboHead.
The SRTH TurboHead from LSP is interchangeable with the T1/T2/T4/T5 and KT1/KT2/KT5 and the 12PM/12ZM/Leopard.
There are two major styles of collar that attach the TurboHeads to the "Standard Body" The "KT" collar and the "Classic" collar. All TurboHeads that use these collars are interchangeable.
The T3 only fits the 9N
The KT3 only fits the 9AN
The T5 collar only fits the 8X
The KT5 collar only fits the 8AX/8NX
In general, the SRTH is better suited to the N2 lamp - over the years SureFire have experiement with the stochastic finish of the reflectors. Now-a-days the finish is more pronounced because the larger filaments of the modern lamps require more scattering. As a result, the "T" and "SRTH" TurboHeads general have a longer beam throw when using the very smal filament lamps such as the N1, N2, N3 and N5.
