The Q5 in "RC-29 Q5"? No, thats the emitter used. Theres other Romisen lights with emitter specification on the body in the same way but they are sold by Shining Beam.
But If there's an RC-R5 then that is the model number and probably not an "XP-G R5" emitter. (There is an RC-R4 and it doesn't have an XPG R4 in it)
I was mostly just kidding, mostly. But in general these are chinese companies, so who are you to tell that the model/label on the body has to match what's inside?
