bought this and wired a standard home lamp directly to a 12 volt battery. lights turn on and run for about 2 minutes then dim to about 1/3rd of original brightness. Any suggestions?

I expect yours is defective. Mine runs continuously on 14vdc from a little wall wart powersupply. A 12v lead battery fully charged will be at ~13.7 (14vdc). Note that your bulb is also designed to run on ~12VAC from a little transformer and no rectifier like a doorbell transformer. I suspect the bulb would have the same issue using AC power.

Sounds like you are having a heat related problem with the bulb itself. I'd say it's defective. I have no such performance with mine running on 12v marine batteries in my boat.

Check your power source. Make sure it's strong enough. Maybe you just got a bad bulb ! Mine is still working fine.

No real suggestion. I presume 12 volt car battery. Possible poor connection? Current should be less than 12 amps. Mine stays bright for hours (should get > 100 from deep cycle marine battery).

I am not having that problem with mine it has not blown any circuits, it is plugged into a timer and then into a wall outlet. However mine does flicker and dim on occasion and I am not sure why. I check the connections and it seems fine then one day it is bright again.

From my experience with these lamps, definitely not dim-able. I unknowingly installed three lamps on an toggle switch type electronic dimmer. Since I have surveillance cameras monitoring the illuminated area, we noticed after several hours of use (at approx 95% on) they started to flicker on off than just died. The vendor did replaced the " defective" lamps without issue. However, it wasn't until i installed the replacement lamps that I realized that the toggle switch was actually a dimmer and the people that turned the light on were inadvertently not turning them 'full on' causing the premature failure.

As long as you start it in regular mode high it won't dim. I'm only dim if started in dimming mode (straight up and down)

This is suspect. I would check your volt meter....put a load on the relay and measure it again...its a standard relay and there should be no voltage present. I have encountered mystery power from leads before...but I think its just erronious readings from the meter....are you using a good quality meter? Fluke? Klein? Can you hook a miniature light bulb or LED up to the relay leads and see if there is enough power to activate the bulb? Also how much voltage are you using to power the beam sensor? I used a 12 volt dc power supply with great results. One last thing. Connect your switching device and measure the voltage again. My bet is its gone.... This is suspect.

I bought one bulb at Lowe's; it obviously was a 12 volt. I have tossed the old lamp, and bought a new one. End of story.

It is probably the crappy dimmer they use. I bought a cheap in-line switch and simply cut the dimmer-switch out. I also replaced the bulb with a 2.6 watt LED from ebay. Now I leave it on all of the time and it uses almost no power. (If you go with an LED try to get the shortest one you can. E12 candelabra base. And small LED's do not work well with a dimmer. They tend to flicker.) Good luck

The fact they are LED they will not draw as much electricity as a luminescent. With fresh batteries I have had the lights on for 4 hours. The next time I used them for two hours with no dimness of the lights.

I had the same problem with one of the exterior lights it was controling. Seems like a tiny amount of 'current' was still running through it, even when off.I changed the incandescent bulb to a compact florescent bulb. Now it seems better.

You might try installing a dimmer like Lutron MAW600H-WH Electronics Maestro Duo Dimmer, White single pole switch Often times, it is not a problem with the fixture but the bulb which is only rated to 120V as opposed to 130V. I find a switch that gradually brings the bulb on will greatly extend bulb life.

I had the same problem. I wasn't able to dim the bulbs, unfortunately I waited over 30 days to try them out so I was not able to return them. I am not an expert or electrician, but I think it has to do with the type of dimmer I'm using - apparently some dimmers don't work with LED lights. I think the problem intensifies if you use them like I intended to use mine, which was on a track light system that has a combination of halogen lights and LED lights.

It is possible that your light requires a constant "current" source (since you mentioned 32-36V), instead of a constant "voltage" source. This is a constant voltage source, 12VDC.

If you are using a dimmer switch, there may be some electrical current leaking through the dimmer switch circuit. If you're using a regular on/off switch, then possibly some residual energy is residing in the lamp circuitry and should eventually extinguish.

I charged the light for 24 hours and "pushed" the "on" button a couple of time s to get it to work...has been fine ever since. Sorry I can't help.

I bought mine a couple months ago and the light worked for a couple of hours then never again. It was an electrical issue, not a bulb issue. I wouldn't recommend it....

I just tested this on a 750W bulb. The following behavior was observed: With the dimmer plugged into the wall, plugging in the lamp caused a red light on the dimmer to illuminate. No light was observed from the lamp. Upon moving the slider up a few millimeters I could hear a voltage applied to the lamp, no light though (no enough power). As I moved it up the lamp illuminated. So in short, I think in its lowest most setting you should not have any current. So no power. Update: I just tested this on a 75 W bulb, same behavior.

I had the same problem with my switch trying to use it for a 12 volt outdoor light. Power going in, light fixture works when connected directly to the battery, but timer does not work. I am past the 30 days, so.....
