Question: Can these dimmable using a PWM dimmer?
Document: as 12 volt lights. I'm using them on my boat. They would perform well as security lighting where 120 vac is available.To me it was no big deal converting them, and I ended up with 2 nice little voltage converters.
This LED light is very bright, and I am using it with a small 8ah 12v lead acid battery when I am camping. I plan on eventually running it off a second battery in my truck. If you need a basic light for offroad to light up camp or a cooking area this is perfect.
That 1A or less switching opens up a vast number of relays that can handle 1A at 12V. I plan to build a simple emergency light using these indoors and out, an array of batteries, a contactor for the charger, and a 2nd drop out relay that energizes the lights when the AC dissappears.
Needed some light away from AC, so I bought a dark sensor, a 12V PIR Sensor Dimmer/ PIR Switch Dimmer, a UPG UB1280 Sealed Lead Acid Battery, a solar 12v battery charger, and two of these lights. It lights up a large area of a shared driveway when we are walking. Very bright. The hardware packaging seemed pretty robust and the mounting clips met my needs. Pleased so far.
So for one thing, amazon sent me a different model number than what is listed in the description. The light sent was a 10-30v light. I connected the light using the same transformer that runs a bunch of other LED lights and got a strobe effect. These lights are not good if you plan to connect them to your existing outdoor landscape transformer.
this a great light with plenty of light , it was shipped promptly and packaged securely, can't beat the price and quality
testing a field radio vs an axel for a 2.5 ton truck)  For and IP65+ rated product we normally do shock/vibe, voltage variation, negative 50 degrees C to positive 50deg C thermal operation, salt spray, and other tests. I am simply amazed at the QUALITY that went into the construction of these lampholders. We are starting tests today on a 24 hr run-in test to ensure there is not infant mortality. A full 810 test takes time and I will update as time permits.
real nice product,real bright. it's not a beem of light like  a spot light. L E D is just different.
light is awsome its on T-top on 18ft center console  and we use it all the time  great buy for product vs price
it covers a dying 12VDC battery down past 11V AND at the same time it covers 2 ea 12V batteries in series for a 24-28VDC operation. What is nice about going to 30VDC is that on occasion you need to "equalize" lead acid cells - this is easily done by turning the charge voltage up from 13.8 float to 14.5V (for a 12V battery of 6ea.
Answer: no
