This is my favorite thread about underwater lights. Good luck in your search. There is extensive coverage on this topic. A search will have hours of reading knowledge. https://www.tigeowners.com/forum/gen...pics-and-video
IMO. Blue or a cool temperature white looks best in water. Water absorbs red very fast, so any color that’s has a red component will not appear as bright.....ever wonder why the ocean looks blue??????
I personally am all about RGB leds, but not in water......
But talking lights grab yourself some white or blue liquid lumens and be done with it. Blue looks better, white is better for depth perception when surfing.
Im interested only in the single white color. I noticed one model for example is rated up to 7000 lumens and voltages from 10 to 30 volts. I have to assume the 7k is with 30 volts and progressively less as the voltage decreases. Am I correct about that?
Two things are play here. One is the safe operating voltage range and the other is the color's brightness.
"up to 7000" lumens" Not every color has the same intensity. White is obviously the hottest, so it will have the higher lumen output. IIRC, red is on the lower end of the scale, so its lumens will likely be a little less then white.
RGB lights may also have an "up to" a range of lumens for the same reason. As the light changes colors, the output can change due to the same color temp differences.
"10-30 volt input" Many 12V DC devices are designed to operate safely with a higher then the common 12V DC electrical systems found here in the US. This is to accommodate 24V systems sometimes found in the European market for example. So the lights can be wired to a system that operates are a higher voltage, but the output is fixed, and everything is spec'd at the 12V.
Hope this clarifies your questions.
Further info;
With underwater LEDs, you do get what you pay for. There are quality lights that are budget friendly and they are bright lights that are just plain cheap. You will likely not get both quality and bright at the lower end of the scale.
So if your lake water is very clear, then you can get a quality light with good light coverage at a good price and be satisfied. If your water is murky, Id highly suggest upping the budget for a higher output light. I do not suggest the over the top advertised lumen at the bottom dollar price.
One of the key features you get with a quality light, especially the higher output lights, is some form of thermal protection. These lights relay on the water to cool them With the boat above no wake speed, like surfing at nigh, not that anyone here would ever do that , there can be little to no water around the light to cool it. The thermal protection will either dial back the output or cycle the light off to cool and protect it.

Sorry to derail the conversation on underwater lights... but you have to love the responses, right?! Well done gentleman... and sandm!
My dad would always get mad when I was playing around and he would say,” it’s all fun and games until someone gets hurt”. Of course he was talking about physical injuries as I would be wrestling with my friends and such...... I do enjoy reading everyone’s personalities on the forum....good information and entertainment!!! I hope no one gets seriously offended when we are laughing at each other.
