UV LIGHT VS FLASH LIGHT TEST. DOES IT MAKE A DIFFERENCE?

In morning while its still dark fishing for bait i wonder if UV light would be better than my head lamp charging my crappy jigs and sabiki.. Also when vertical jigging past 200 feet sunlight doesn't hit bottom specially during overcast sky. This is test to see how much of a difference it makes. Make sure its real UV not a black light. Real UV will emit heat. You can get them off Ebay cheap!
