SUPERNIGHT RGBWW LED Strip Light IP65 Waterproof RGB Color Changing Rope Lighting with Warm White 3500K Color 16.4ft 300leds 5050 Tape Light (RGB + Warm White)

Best price for the exact product I was looking for. Great quality as well. I'm using them for a d pillar mod on my escalade. I'll upload pictures when I'm done.

This is a good product for the price. However it has room for improvement, and should be chosen for appropriate applications only. In the future, I will probably use RGB strips parallel to a separate white LED strip to maximize brightness. More brightness could also be achieved by running two (or more) rows of these RGBW side bay side.After playing with various RGB LED strips, I was curious what the RGBW would be like. I used these strips to build a color changing light (with a Fibaro RGBW Z-wave controller) for over my coffee table. I thought it would be nice to have the option of either colored mood light or white light. I took a 4' long strip, installed it in a plastic c-channel and hung it over the table. While the lamp put out a nice ambient glow, it did little more than create mood lighting when the other lights were turned down. I had hoped that it would throw some usable light on my coffee table when the lights were turned down for watching movies. The "white" output of this strip wasn't nearly as bright (or warm colored) as my dedicated white strip lights. This is a result of every other LED being used to produce white light. The "warm white" designation of this product is inaccurate, however considering the cost and that it wasn't well reported in other reviews, this was not a surprise to me nor a disappointment.One would think that turning on all colors of the strip would produce white light, however the blue overpowers the red and green, making the output even more cool colored than the whites are alone (see attached photo.) To get a maximum output "warm white," I found that I have to turn off the blue LED's and dim the green down to 25%. Of the 4 channels of color, you can only use half of its total output when trying to achieve warm white. Turn off the white, and theoretically 100% red mixed with 100% green should produce yellow. The red apparently isn't as bright as the green (or blue) so you have to use 25% green with 100% red to achieve yellow. This RGBW strip is by no means a replacement, or even an upgrade when you are just trying to achieve warm white light.Because the colored LED's alternate with the whites, you get half the brightness when compared to a dedicated RGB strip using the same LED modules. This pattern of alternating white and colored LED's results in output which appears fairly segmented. This can be mitigated through a good installation. If the LED's aren't directly visible and are reflecting off a surface a few inches away, this segmenting will not be apparent. It is most noticeable when the LED's are visible.Splicing and soldering these is difficult, but it is possible. I was able to solder these to the LEDENET extension cable with a good fine-point soldering iron and a moderate level of soldering skill.

So lets take a lesson from what this product is and isn't from an actual electrical engineer:If you think the adhesive will stick to anything, it will not. I knew this going it and honestly no one should ever rely on any stip adhesive, they should be zip-tied or stuck on with another external piece of double sided tape. If you knew this as the other reviews have stated, good on you. The waterproofing is pretty shotty as I have noticed different heights of silicone applied to certain areas where as more often times than not, it's very thin. I would not trust these strips to adhere to anything or stay 100% waterproof (light misting or occasional moisture is fine however if you DO NOT bend these strips at all, other wise the waterproofing is totally compromised).So when they say 12V strip, they literally mean 12V is the maximum voltage apparently. As many of you know this is not the nominal voltage of automobiles, boats, or anything with an alternator and battery setup. I did a current test with an actual legit american made led strip and found that the american made strip could easily handle up to 16V safely as where this strip could handle 12.2V. I use the reasoning that no single LED should have over 20mA of current flowing through it, as to avoid damage (led's can generally handle more but I would never drive any of my projects with more than this). Other reviews have stated that some leds will burn out or turn different colors and this is because they are exceeding this current mark from being over the 12.2V voltage mark. This strip will work great for setups that don't have transient spikes with a regulated/dedicated supply however but for the every day person, this strip will never work in an automobile setup (at least not for very long).For people like me it is no big issue that these strips cannot handle over 12V as there are simple ways of regulating/current driving/biasing these strips with a fairly simple circuit (google it if you don't know). But if you do not want to do these extra steps or do not have the means to this strip will never work for you on anything with a car battery. However, if you plan to use this strip as accent lighting, ambient lighting, or anything that involves a dedicated constant voltage power supply; go for it.All in all it's not a bad strip, just shotty chinese engineering. Bottom line is if you attach these strips with mounting methods and feed them from a dedicated power supply they will work for you. For all of you looking to use these in cars and boats, don't even bother. I plan to use these in my hood vent for my camaro but will obviously be mounting them with zip ties, above the water drains, and with extra circuit protection at the feed end.

This led light wheel does not have the water proof protective cover and does not have a warm white. Its a cool white
