kevin, i’m thinking about doing an IR T20 for shooting hogs. After looking at the thread here , i got a little confused. at post #22, djozz says he is using a 4715s and it is a parallel emitter then later marsh said the S was for the series emitter. So, the 4715S’s that RMM sells, am I correct to assume that they are series? How much current can they handle? On the thread I linked to, They are running in the upper 2’s.
