Can't open fileNot mine but I’ve seen this
Never had to use a pump up lantern but we did use the foil on the back and duct taped the hanger to make a handle that wouldn’t get too hot.We used to gig with home made gigs and single mantle Coleman lanterns full of Unleaded gasoline and you had to pump them up with a little thumb screw that had a vent hole in the middle so you’d have to quickly use your thumb as a check valve to pressure up the tank. Tin foil on the back of the globe for a reflector, a coat hanger and piece of water hose for a handle and we lit them with matches. Those were the times man. My father had me by his side gigging around 5 years old.
It’s all about the spectrum. Green and yellow penetrate water the best. The reason lots of people have the wrong impression when it comes to LEDs and how well they penetrate water is either because they only think of the super white cool white or they tried using them above water or both. Halogens work well because they are more yellow and the light penetrates the water with less glare. The same goes for green and under water. The yellows and greens don’t reflect back off the particles in the water and give a clouding effect like cool white will. I like green for super clear and a little iff color water and warm white for the murkier stuff.That’s pretty impressive man, never saw the green floundering. Looks good.
