Those are both great lights. What the lunes. I think scorpion is 350 Lumens and other 180 Lumen ? I’ve use Streamlight over 35 years as first responder. SL20 and the head cracker SL35. Stringer SL15. I trusted my life many days to them. We had the box type as well on Fire Engines. I still have sl15 and couple sl20. I’ve been using the 4hd 3500 lumes and strion 500 lumes. I’ve used the pistol lights as well. Be great buy on quality lights.
