Suptig video light test Avril Keith

after buying this cheap light from an online auction site, i put it to the test beside my qudos knog lights x 2 The suptig light cost approx £14.99 from china and each of the 2 knog lights cost £79.99 each from the UK. using my gopro hero4 on a tray ontop of the cheap light and my knogs on 2 arms, i have shut the lights off to show the cheap light working at full power and half power...the water was a chilly 7 degrees in loch long today...so i didnt stay in too long.
