Flash bangs have long been a important tool for law enforcement officers to distract and disorient hostiles in dangerous situations. The concussive force expelled by flash bangs provides crucial seconds that can be the different between life and death of officers, hostages and suspects. However, this same concussive force has the potential to cause harm to everyone within its blast range.

This is part of the argument River Rock Designs is using to get law enforcement to take a look at the DELTA (Dynamic Entry Lighted Tactical Accessory) Light Ball. I haven’t even gotten to see one in real life and I already see huge potential for home defense. I want one of these in my safe next to my Colt. In fact, I want two of them.

The DELTA Light Ball is built with a tough polycarbonate outer shell and disorients bad guys with a 400 lumen strobe effect, ending with full illumination of the target area. The DELTA can be thrown through windows and evenused in conjunction with flash bangs by police and military.

"The DELTA Light Ball will make many rescue, search and entry scenarios much safer for all involved, and yet still affords the use of more aggressive devices if necessary,” said John Sedovic, president River Rock Lights.

While designed for law enforcment and military, the River Rock DELTA Light Ball will be available to civilians. The only question is when. Hopefully, I will be able to follow up on this story with actual results from testing this in a variety of situations.
