Pros: I haven't the right tools for proper mesurement but I'm pleased with how much light is output. When I told my wife I bought something from the USA, she said "Oh not again!". When I showed what it was, she said "How much ?" "10$" "Why didn't you buy some 3-4 more, it'd be great for the kitchen or somewhere ??!" "!!!"
The bar worked with a +6V gel battery I had in my garage. Couldn't see much difference between 6V and 12V so I wonder if I'll use 12V after all...

Cons: I didn't see the bar was sealed and not flexible at all, I wish I could individually rearrange the LEDs to make a panel. Bah, I'll change my project !

Other Thoughts:

Bottomline: Great buy, DX is simply great for us tinkerers, since the traditional (local) stores continue selling the old generation gadgetery at kidney-breaking prices (LED bulbs and all).
Will probably buy some more when my wife will know that at this price, shipping is included.

Pros: - Very Bright
- Well Constructed
- Lightweight

Cons: - Bar came not so flat
- Bar Wires could be Red and Black for easy plug ( Actualty they come in White ( negative ) and Grey ( positive )

Other Thoughts: No other thoughts, the product is simply amazing for the light it produces and the effect that all your friends will have once see then installed.
The product is "designed" for Car Lighting, but I think the same bars could be anounced on the Interior House Lights for Houses.

Bottomline: Great Bars, I installed then in my kitchen, Light are very bright in WHITE, it´s color temp is like a Xenon-HID 6000k to 8000k. I also upload the photos to DX for publication.

Pros: Good quality bright, white light better than a fluorescent tube, but with one third of consumption.

This unit has 2.4W of power, while a tube fluerescente of 8W illuminates less than him.

Cons: The positive pole is NOT identified, both wires are white. This poses a risk, if connected reversed and exceeds the maximum reverse voltage of LEDS; they may be damaged.
Therefore, it is necessary to identify the cable positive, applying a lower voltage, 10V.
The absence of documentation prevents from knowing the maximum voltage ratings, so we do not know if it can be damaged with voltages present in the 12v electrical systems of a car, caravan, boat, which can exceed 14V when charging batteries.

Other Thoughts: Other reviews recommends using a 5 Ohm resistor in series, to protect the bar leds versus tensions over 12V.
This is not the best solution, because the resistor can cause a voltage drop of 1V at 200mA.
I recommend using a low dropout regulator, as LM2940CT-12.
I do not recommend regulators as 7812, as its voltage dropout is very high (more than 2V).

Bottomline: I'm using it to replace 12V fluorescent tubes on my boat.

Pros: Sturdy construction which feels quite good quality.

Cons: Not very flexible so this would be ideally used as a straight strip potentially to replace fluroescent tubes. I ordered two strips and one of the strips was faulty with 3 leds that weren't working. I notified DX but they were quick to respond and were happy to replace it.
Not ideal for automotive use out of the box. Would need to add a resistor or a zener diode in series with the strip to avoid blowing up the leds.

Other Thoughts: Would be fantastic if DX supplied this with a resistor/diode wired up in series so we can use it on cars/trucks, etc. Just another hassle to obtain the correct resistor or diode.

Bottomline: These strips look quite nice and put out decent lighting. Would be great for caravans or interior lighting for cars.
