How many lumens should a dive light be?
For night dives in clear water if you shine your torch on the white sand or even on your gauges you’ll blind yourself with anything more powerful. Brightness in the shade is 1,000 lumens, while in places with large areas such as highways, the brightness is 6000 lumens. Below 3500 lumens, our eyes feel comfortable. When the brightness of direct or reflected light reaches 4000 lumens, the human eye starts to struggle to receive light.To put it into perspective, imagine the brightness of a standard 60-watt incandescent bulb, which typically emits about 800 lumens. Now, multiply that brightness several times over—that’s what 5000 lumens delivers.Yes, 100,000 lumens is extremely bright and would be too bright for most indoor or outdoor lighting applications.Lumens Lighting that exceeds 20,000 lumens is considered high intensity and special pur- pose lighting. Lumens measure brightness. For example, a 60-watt incandescent bulb produces about 800 lumens of light.Q4: Are 20,000 lumen headlights illegal? Yes, 20,000-lumen headlights are typically too bright for legal road use anywhere. Most jurisdictions have regulations on the brightest headlights to prevent blinding other drivers. Average legal LED headlights usually emit somewhere between 2,000-4,000 lumens.
Can LED lights work underwater?
Because of their excellent vibration resistance and long life, under- water LED lights are also used for thru-hull applications on recreational boats. K daylight can illuminate things clearly within 500m, allows you to use it as a tactical long-range flashlight.Super Bright Flashlight 500000 High Lumen – Flash light powered by LED Chips, it can support up to 500,000 lumens output. And the maximum illumination distance can reach 3280 feet(1000meters), could illuminate a wide area of 5000 square feet easily.The Floating Flashlight is a water-buoyant LED flashlight that is great for boats, fishing, and other water activities. Bright, clean light, up to 28 lumens and runs 26 hours continuously.Generally speaking, entry-level diving lights and flashlights with 700-1000 lumens can meet the basic needs. If it is night diving, deep diving, cave diving, etc.
Do underwater lights bother fish?
Here’s the quick answer: No! While it may seem strange to have a light bulb under the water, Underwater Fish Lights do not harm fish. Koi fish have good night vision and can navigate in low light conditions. They do not require bright lights to see at night.

What color light is most visible underwater?
Red and orange light waves have less energy, so they are absorbed near the ocean surface. Blue light penetrates much farther, so blue objects are more visible in the deep. Red is the first to be absorbed, followed by orange & yellow. The colors disappear underwater in the same order as they appear in the color spectrum. Even water at 5ft depth will have a noticeable loss of red.The longest wavelengths, with the lowest energy, are absorbed first. Red is the first to be absorbed, followed by orange & yellow. The colors disappear underwater in the same order as they appear in the color spectrum. Even water at 5ft depth will have a noticeable loss of red.You will notice that many of those colors are much harder to see under water when there is surface agitation. The hardest colors to distinguish are the light blue and white.
