This is easy. Brass Fireflies PL47mu. SWEEEEEEEET. 
Edit: Just saw you said 18650 light. PL47 takes both 18650 (w/ adaptor) and 21700 sized batteries.
Edit #2: It’s also 15% off until the 10th, so final price is $63.75. That’s not too shabby at all.
Looking for a single emitter 3000-4500k tint light. Copper preferred.
