After a few times of using it light stopped works. I don’t know if it is Transformer , definitely not connections, very very disappointed with the productEverything about the light is fine but,,,, very disappointed that the remote does NOT have a battery even though they went through the effort to put in the plastic separator so that if there was a battery it would not have contact . Nice try but would have been nice to know the battery was not included and what size battery do you have to buy.Awesome light effect on my 215 ec sea ray.Heavy feeling construction.Anyone with semi electrical skills will have no problem to do the installation. I fed mine off the stern light, that way it's already hooked up to a switch. Unfortunately the finish on it tarnished after the first few hours of use in freshwater.Hopefully the waterproofing will last and won't start leaking.There is Know company info to ask any questions. If any one from the company see this please respond to this review. I bought this in April but didn’t put this product on my boat until last week. I believe the remote is not working. It only display red and the indicator light on the remote does not light up. It said that my return policy day is over I don’t want to return it, I just want a new remote that works . If I could get a new remote I will change the stars if it works. As of now it’s not working and 1 star is to high of a rating. Also if someone installs this product, it says not use an sealant, it does not come with a rubber gasket so I use Teflon tape. I have no leaks. That was my biggest concern when I bought this .Functionally, great item. My ONLY complaint is that 27w should be clarified as it does NOT operate with 27 watts. Because it is RGB, 9 watts is the average as only 1 row lights at a time. There are however some settings that utilize PART of all 9 bulbs although clearly not at full power. If it were a true 27w set up it would be a steal at the price. Easy install as well.The light is cool, remote showed up broke, and the plastic devider for the battery was there but must have been Friday , cause no battery. Plan on a batteryAt first I was impressed. It was easy to install and provided adequate light (not super bright). My first minor complaint was with the IR remote. Even with a brand new battery in the remote, you needed to be 3ft or closer to the IR receiver for it to Work.After 3 months, the light completely stopped working. When the boat was pulled out of the water, I noticed it was completely corroded. This thing was a complete waste of money.DO NOT BUY.I ordered one and the red didn’t work and was not bright. They give me my money back and I ordered a second one. Took the boat out once noticed there was water inside the light bulb area and it was all foggy in after the first run the lights did not work. I have sent two emails about the second one and this time I have had no reply.
