NAOEVOLed Boat Lights Waterproof, 6Inch 34W 4200LM Marine Led Light Bar, 150° Flood Beam Marine Lights for Boats Pontoon Deck Dock Truck ATV Jeep Tractor, 1 Year Warranty, 2 Pcs (White)

These lights are nice for lighting an area with their wide flood beam. At ~15 watts apiece, they're not incredibly bright, but they complement each other and have a white/blue 6500K color. I've used many lights with the same form factor and mounting yoke, but these are the first I've had with a flood pattern, not a spot pattern. The included mounting hardware is stainless, and a hex wrench is included for the side screws which control the friction of the vertical adjustment axis. I did find these holes were not easy to screw into, probably because the paint was applied after the holes were drilled and tapped. I had already applied anti-seize to corrosion proof between the screws and the aluminum housing, and with a little in and out screwing action, was able to get the screws all the way in to tighten against the bracket. The wire is only ~10" long of somewhat thin 20AWG wire, but it seems like quality tinned copper conductors. I spliced mine to Deutsch 2 pin connectors for a waterproof yet detachable connection. I'm using these on the side cranes of the boat to provide extra illumination while transferring salmon, which often is a job done at night from boats which are reluctant to turn on their own deck lights. The low amp draw is good because it must be carried through the slip rings in the commutator of the crane, also why I'm pushing them with 24V and aren't as concerned by smaller wire sizes. Gone are the days of halogen lights which perform best with super heavy conductors. These LEDs will shine the same when fed with 10-30VDC, so staring at 24V there can be a lot of voltage drop before they consider dimming. I'm pleased with these lights' performance, and hope they last a few years in the salt environment. The price seems quite reasonable for a marine light, and I would probably order them again.

I picked these lights up for the back of my pontoon boat to light up my catfish rods. Holy cow do they light them up! These things are extremely bright for their size yet use less battery than I'd expect. That being said, you definitely want to have them wired to an auxiliary battery and not your starting battery if you plan on keeping them on for a while. These also help me a lot record my night time fishing trips since GoPros need a lot of secondary light to have anything useable. My rods have never been so visible at night! I usually turn them off in between just because of the bugs being attracted to the light, but when they are on I can see everything. Definitely avoid looking at them even for a second though because you won't be able to see anything for a while.They are well sealed too and I can't imagine they will fail very quickly like my last set. The powder coating is thick and smooth. The included hardware is all true stainless steel and hasn't rusted at all. The fins on the back of the lights dissipates heat rapidly so everything about these are well made. These are definitely more flood lights than spot lights so they work as advertised. Worth the money for sure!

I ordered these lights to mount on the forward edge of a hard dodger I’m building on my sailboat for illumination when entering marinas, traveling along channels or any other time the vessel is close to hazards in the dark. Such lights can be particularly useful lighting reflective surfaces on aids to navigation in channels, although a spotlight is needed to reach out to longer distances. The lights are very bright and adequate for my intended use (I have no way to measure lumens) based on bench testing I conducted on a dark night from an elevated deck rail. However it is important to understand these are flood lights with limited range, not spotlights. The light spreads rapidly both laterally and vertically so much of the illumination is wasted diffusing into the sky or into nearby water. They would be better suited to illuminating the deck from the rigging (the boat already has spreader lights).As noted I have no way to measure lumens but I did bench test to measure current, thereby calculating watts (pictured). Using a 12V power supply my meter measured 1.45 amps on both lights, which equates to 17.4 watts (P=IE); half the power listed for these lights.The lights seem to be robustly constructed and well finished. Testing of mounting hardware with a magnet evidenced negligible magnetism which is consistent with marine grade stainless steel. Note that mounting screws screw into the aluminum body so you can expect galvanic corrosion around the threads in a marine environment absent protection. Use of Tef-gel or similar products during assembly can control the problem. There is no breather valve to relieve pressure within the IP68 housing. However cooling fins are large so that may keep temperatures, hence pressures, manageable; time will tell and I’ll update this review if needed.I ran into problems attaching the mounting hardware because the screws which screw into the light body were very difficult to install. I believe this was due to finish paint which was coating the internal threads, though I can’t rule out poorly formed threads. First being careful not to cross-thread the soft aluminum body threads I spent quite a bit of time working the screws into the holes forwarding and reversing many times, as with a tap, to clear the threads. Eventually the screws screwed in fully and I was able to attach the mounting hardware (pictured). The included hex wrench was too short to be used easily so I used a long 4mm hex wrench I had on hand (a 9/64” hex wrench would probably work OK as well). These screws were a serious nuisance to install and one reason I removed a star from the rating.I believe these lights will serve well in their intended role. As noted, I’ll update this review if needed.
