Question: Is it possible to attach this product to a portable battery pack so that the object you use it on can be mobile?
Document: These LEDs came in today are very bright. I have them connected to my 12V solar battery pack and use them for evening lighting in my backyard. One end has bare wires and the other end has a round dc connector. The full string, when plugged in uses about 20 watts of 12v DC power. This is not lots of power but the amount of light it puts out is significant, easily lighting up my entire deck.
As advertised. I've got this in my portable fish house and it works great. I soldered some ends on it to hook up a dimmer and to my 12v battery - works great.
This item came with a 2 year guarantee from HitLights in the packaging. The product worked when I received it but wasn't quite as bright as similar products (same specs) I have bought in the past. It was usable however and I installed most of the roll.After just 2 months of use the LEDs had become VERY significantly dimmer to the point where the product was no longer serving it's purpose.
It works well. My only complaint is that there is no instructions with this product which show you how to make the connection. It's not hard but if you haven't done it before it can take some time to figure it out. This especially true with this weatherproof LED since it's covered with thick silicon housing. You have to remove this and expose the connection in order to use the recommended PCB connectors. I wasn't sure about this but luckily I found a youtube video which shows this.
The answer is a 100% yes! There's NO tricks or catch to this product, you literally get 16.4 ft of LEDs (I measured), I got them quick, I tested them, they work just as I thought and they are VERY bright and versatile! One led light was out but that's not bad considering I am not going to use all 16.4 feet, and for the price you can't beat it.
A great product. Easy to use and puts out a tremendous amount of light for a very small amperage draw. I installed 2 sets in my camper and they light the entire space. No need for the original 12 volt lights.Make sure that you clean the surface before using the sticky tape for a good grip. I also have 2 sets that I purchased over a year ago that I use quite frequently and they are still working great.
overall great product, great packaging, tested the whole strips and one section of the led strips were blinking off and on, possible defect (minus one star). I had to order this twice, the first time when I checked my tracking it said it was shipped, i waited two weeks to see if my product came in, nothing came in and it was one week past my delivery date.
I used this inside my sailboat. Great source of light and easy on the battery. Extremely easy to wire in and look great.
As described and working great on my RV. Very bright LED lights. The self adhesive backing does not stick well for outdoor use.
using this on my salty tank. works great and goes together very easy with the recommended link clips. will be ordering more for other  people to use on their tanks.
