450 Hour Water Activated Diamond Commercial Fishing Strobe LightsI recommend these inexpensive commercial lights for daytime swordfish deep dropping, as well as night swordfishing applications. Excellent for use with fishing lines of 130 LB test to unlimited class.I just concluded testing on these lights. I dropped one in a glass here at the office on 8/25/2016 @ midnight and it was finally done flashing on 9/13/2016. I wasn't watching when it finally went out, so I do not have an exact time, however, the light flashed continuously for at least 19 days, giving it a rating of at least 450 hours. In addition to testing them for time, I also placed it in our weekend beer ice slush and it worked just fine in the cold water. The solid diamond construction, these lights can be dropped down to 2000 feet.
These lights must be stored individually in their own bags. Storage must be dry. These lights will self-activate if stored in a groupand greatly diminish their battery life.
