Question: I just received 4 of these LED lights. They only have a blue and red wire. How do I connect these lights?
Document: Haven't tested over to long term but they appear reasonably well made, but I don't thing they put out nearly the light a 10W LED should. I have 3LED flashlights that put out easily 5 times the light. Also a very blue/white light, not warm at all. Also has very short wire with odd colors and no documentation. It has a Blue and Brown wire???? Picture shows Black and Red which actually makes sense, but Blue and Brown.
Update April.. My light has started to flicker like some other reviewers noticed. While I love the light this makes it unusable. I am going to order another and hopefully it will not flicker or I will trash these and buy a different LED light. These are a great buy IF they work but even a low price doesn't justify an unusable product.I received today after a 2 week wait. Mine had the 3 wire wire with Blue/brown being the power connections.
The Pigtail is about 10 inches long and has a blue/brown wire set up. Not much to work with, but I can deal with it. Some mouth breather cross threaded the screw that holds the mount on. He forgot one lock washer too. There was no mounting hardware. As a someone said earlier, the chip inside the unit is is covered in some crappy tape to isolate it. The chip is just hanging in there,free to shake around.
This is the worst product description i have ever seen on Amazon. I have bought a lot of things on Amazon and this is truly a huge disappointment. First of all the picture shown is silver and it shows two wires in the picture one black and one red which is what it should be for a 12v light. I opened my box and the lights were black with a 110 plug on them. This is not a 12v light like the description indicates.
I ordered four lights. It took a long time to recieve the lamps. Two of the lights performed beautifully giving a lot of light. One light flickered at all times and the other seems to have a defective LED giving only half of the light intensity. I communicated via email several time with the seller and they promised me to replace the lamp, but I am still waiting after over two month for the replacement lamp to arrive.
This light itself if well constructed from aluminum. Well sealed against the elements. It produce a great deal of light. The unit contains a lens that focuses the light into a spot light, not a flood light. However, the lens can be reversed to produce a wide angle. The light produce is a pure white light.I added this to an existing set of dusk til dawn LED path lights to illuminate the driveway, mounted under and eave about 15 feet off the ground.
Nice AC/DC light that draws 800ma @12.5V DC. You can reverse glass lens and have either narrow or wide beam. I have tested them with the AC lighting outpu on my snow blower and they have better light output than the OEM lighing system. Hopefully the alternator system has enough current to handle two lof these lights, if not I can run them for over 2.5 hours from a 4.5AHr battery.
received the items on a timely basis. I have not hooked them up so I cannot tell you how they function.
I use it on the back porch of our remote hunting shack. Turns night into day. Very easy to wire and mount.
These were easy to wire, quick to mount and put out A LOT of light. I had to put a dimmer on them because they were so bright - good problem to have IMHO.
Answer: yes
