HI Donn
The beam shots were taken in a KT5 but they are great in a KT4 also. If anything they are a tighter beam in the Kt4
How well will these work in a KT-1 head?
Thanks
Can these be cut down to work in a non-turbo M3 head?
Got my XPG R4 5000k tower module :twothumbs
Definitely out throw my other SST-50 D26 Dropin
Excellent tint and output
Thanks Dave
Hi, Nailbender
I have two mid to late 1990's vintage 3" SF Turboheads (as compared to the more modern 2.5" heads). These smooth finish 3" turboheads throw further than the more modern heads.
The 3" turbo heads nominally support N1, N2. MN15, MN16, MN60, MN61 and N62 LA's. I was happiest with the N62 beam, but th N62LA was discontinued years ago as it was specifically for the 12pm/12pz. I currently run one of the 3' turboheads with a 225 Lumen MN60 and the other with a 350 lumen MN61 driven by 3@ 17670's in a ridiculously long 12PM body with extenders. The MN60 beam is fine but the various MN61 bulbs have a somewhat messy hotspots. Worse, I am afraid to run the MN61 for as long as the rechargeables would allow because the old 3" turboheads have lexan lenses which might not take the continuous heat.
The MN60 has a more compact hot spot and throws farther than the MN61 with each 3" turbohead.
I think I'd want either or both the XP-E R3 or the XP-G R5 with the 1-level 4 to 14 volt 1.4 amp driver. Would it make sense for me to lend you one of the 3" turboheads to decide how much shimming you needed for the tower module, or does the preceding suggest that your basic modules would be fine?
If you did not mind sending it would be best as it would allow me to shim for maximum throw. These may work but I am not sure. I have a 12Z but it has the 2.5 inch head not 3 inch. I am not sure how much difference that would make.
Sending one takes the guess work out of it. If you decide to do that PM me for addy.
Am I correct in thinking that at 1.4 amps the XP-E R3 would be in the 270 lumen range and the XP-G R5 would put out about 320 lumen?
You are correct with your thinking on both. You are right on the nose with those lumens OTF.
Thanks for your comments.
FWIW..I just tried one of Dave's XP-G R4 towers in a SF 3" TH with VVLOP reflector. The focus was perfect, projecting a needle beam with a ~1' hotspot at ~15'. I can't tell if there is shimming under the emitter board, because I don't want to remove the tape.
Hi Dave,
My XPG R4 1-level 4 to 14 volt 1.4 amp tower module works great with the Surefire M4 host.
I wonder if I can use this module with Surefire M6 host?
I am not sure if the current on the M6 is too high for the module.
Thanks
