EMITEVER 24Volt LED Power Supply Driver 12W 2-Pack, ETL Listed Waterproof IP67 Low Voltage Transformer, 120V AC to 24V DC Converter for LED Strip, Spotlight Cabinet Tape Lights and Outdoor Lighting

Updated Review (02/20/2024)An EMITEVER representative reached out to me, offering to refund or resolve the issues. Their Rep added a PDF "User Guide" in this listing, which includes the install instructions. Their Rep also removed a Q&A item which suggested that this item is usually installed inside a junction box. Bottom line: (a) EMITEVER customer service went the extra mile to resolve a customers concerns, and (b) they added accurate install info. I can't judge how well these work since I returned them without installing them, but everything else was "5 star" quality. The item itself, looks well made.Additionally: One should be prepared to install this power supply someplace not flamable (i.e. not wood, or near something cumbustable), or enclosed. The 120v wires need to be inside a junction box for code compliance, but the power supply and DC connections will mount outside a box (i.e. for benefit of air flow and cooling). I was looking at replacing my existing plastic junction boxes with metal ones, and attaching these to the outside of the exposed, metal junction box. I imagine that these could also mount inside a computer cabinet if it had internal cooling (i.e. fans).Original Review (02/10/2024)Bought these to use with WIFI light strips, to mount under kitchen cabinets, inside a 1" high junction box. The description of this product includes "Q&A":Q: Is this to be mouted in an exposed location, or must it be in an electrical box/enclosure?A: It is usually installed in the junction box or within fixture housing.So, ok, I'll install them inside the junction box, hardwired (120V), and attach the DC leads to the strip light controllers. Ez peasy.However, the instructions INSIDE the item when received tell me:"Cooling by free air convention", and "Always keep good ventilation; keep the heat dissipation space big enough". As in, INSIDE A JUNCTION BOX? I highly doubt that there's any ventilation inside a junction box.Which makes sense, i.e. the aluminum exterior needs air to cool. So, why did the Q&A recommend putting inside a junction box? Maybe it'd be fine with a 2 gang, metal box, but must junction boxes are plastic.Ok, so, we'll mount it outside the box, as long as the wire nuts are inside the box, we statisfy code. Wait a second. Not it says:"Do not mount on wood or flammable surface. Keep minium 4CM or 3CM for LED power supplies each other." So, external mount on the WOODEN cabinets are out, too.Unfortunately, my electrician installed a common, 1" H x 4"L, x 2.5" W, PLASTIC junction box. I may buy an aluminum version (very hard to find, but I found some for about $10 each), and try attaching this power supply driver to the exterior. Of, I may return this, junk the strip lights, and just buy a conventional, direct connect 120V light strip or kitchen lights that require no driver.These look well made. Can't tell if they work well. I ~~ highly recommend ~~ Amazon add a PDF with those install directions to this advertisement, for context.

I Needed a new led driver and this matched perfect. Worked great!

6 months in and the outdoor fixtures I used these on are still shining bright!

The 12W unit is nice, compact, and silent. However, there is a noticeable delay (well over one second) between powering up the driver and the LED strip lighting up. This was too much for what we wanted. Interestingly, the 36W version of this driver has a much less noticeable delay (split of a second), and we ended up going with that version and over-provisioning a bit.

This is a well made, compact power supply perfect for using with a relay to provide power to a thermostat and relay coil allowing conversion of an electric heater from a Line Voltage type thermostat to a standard 24 V thermostat. Plenty of power for a Honeywell T5 thermostat.Those who know HVAC, know that normally a thermostat is 24VAC not 24VDC; however, smart thermostats convert to DC immediately anyway, and this has plenty of power to run the thermostat and a relay conversion coil.Nice and small, I was able to wire it into the input to my electric heater, with the relay and all and had plenty of room inside the panel of the heater to hide everything.

I got them at the end of January and they have all gone bad and i am past the return time. All the light are blinking. Very disappointing. I would not recommend to buy.

Works great in my LED coach light. Just make sure to get the right voltage unit for the light that needs repair. Would recommend.

I got the 12v version and used it to power a 9 foot strip. Worked fine for 6 months, and now it flashes constantly. There is no way to use it unless you like blinking light strips.UPDATE: the vendor reached out to me and offered a refund. This is a good offer, but I really wish it just worked as intended. I appreciate them owning their product and the outcome is great! Good CS - I did not reach out to them, they responded to the review.
