I wanted to have daylight bulbs, which I could only find in LED; I figured this would be better anyway due to lower power usage. Unfortunately, the original transformer did not work properly except at 100% brightness. Otherwise, it would make an extremely annoying buzzing noise. I struggled to find a 12v LED dimmable transformer that would fit inside the enclosure required until I stumbled on this. I was a bit worried it might not work as they say it’s only for LED strips and no info on compatibility with mr16 bulbs. Regardless, I gave it a shot and it did end up working great! It has only been in the unit for about a day, but I’ll report back should it end up failing. Review: Great- smooth on and off as well as dimming - Bought that a while ago for a living room LED pendant I made myself. Awesome driver as it lets your dim with a standard wall dimmer. Only one caveat - my dimmer eats a bit of voltage (Max is 102V or so) so I don't get to 100% brightness as in my other projects but probably 80-90%. But thats not the transformers issue but the dimmer. What I really like is the smooth on off function. ## Features - Compatible with most dimmer switches, triac dimmer, ELV dimmer from most brands, for forward phase dimming - Dimming Smoothly from 1-100% for 12 Volt DC LED lighting, new dimming technology, with stable and no flicker - Work with 12V DC LED light, such as: LED Strip light, cabinet light, Puck Lights, Rigid Strip Light etc - Compact LED driver, small dimennsion L4.23xW1.71xT1.26 inch, suitable for tight space installation, easy for wiring with your 12V lighting - Fully potted for waterproof, can be used at wet or dry location, full protection: OVP, OCP, OTP, Surge protection, good to power up your lighting, for home or commercial use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KBSVK6R | | Best Sellers Rank | #295,788 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #442 in Lighting Low Voltage Transformers | | Brand | E ENERSYSTEC | | Brand Name | E ENERSYSTEC | | Current Rating | 3.4 Amps | | Customer Reviews | 4.2 out of 5 stars 65 Reviews | | Included Components | 12 Volt 40W LED Driver | | Item Dimensions D x W x H | 1.26"D x 1.71"W x 1.26"H | | Item Weight | 8 Ounces | | Manufacturer | Enersystec Electric Co.,Ltd | | Maximum Frequency | 60 Hz | | Minimum Frequency | 60 Hz | | Model | e19c309d-acf0-421e-aa47-d9f3ef6a511f | | Mounting Type | Surface Mount | | Part Number | EST-P1240D | | Power Source | Ac Mains | | Product Dimensions | 1.26"D x 1.71"W x 1.26"H | | Specification Met | Ip66 | ## Product Details - **Brand:** E ENERSYSTEC - **Power Source:** Ac Mains - **Product Dimensions:** 1.26"D x 1.71"W x 1.26"H - **Mounting Type:** Surface Mount - **Current Rating:** 3.4 Amps ## Images ![12V Dimmable LED Driver 40 Watt Triac Dimming 12 Volt Power Supply IP67 Waterproof Adapter 3.4A, Constant Voltage 40W Power Converter,120V to 12V Low Voltage Transformer - Image 1](https://m.media-amazon.com/images/I/51r4D8kYIDL.jpg) ## Questions & Answers **Q: I got it with a 12v led strip but it only delivers 8v if i measure the voltage right on the strip. i measured a 2a pull on 12v of the leds separately.** A: If you put a dimmer at input of LED driver, the dimmer will reduce the 12V voltage for dimming function, So you measured the 8v that is normal, it is means the LED driver started the dimming functional, **Q: Will this work to power a ring video doorbell** A: If the doorbell is working with 12V DC, then this power supply is ok for use, You need the doorbell spec, to see it is working with 12V DC or 18V AC, If it is required 18V AC, 15V AC etc, this power supply will not suitable for it, This dimmable LED driver is mainly for 12V LED Strip Light, cabinet light, **Q: This buzzes pretty badly, can you recommend a dimmer that pairs well with it to eliminate the buzz?** A: Dear Customer, Thank you inquiry our dimmable LED driver 12V Waterproof IP67 UL listed, As indicated on the packing label, you can use those recommend dimmer switch, This dimmable power supply compatible with most brand dimmer on the market, Thanks, Figo **Q: Will this work for mr16 LED bulbs on a track lighting setup?** A: Dear Customer, This dimmable LED driver 12 Volt DC is mainly use for 12V DC LED strip light, LED cabinet light, LED module, For MR16 LED bulb, perhaps it is not working with this dimmable LED drivers, Because the MR16 LED bulb has an custant current LED bulb inside the bulb, and that LED driver is not dimmable, In other words, 99% MR16 LED bulb is not dimmable, ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works on dimmable mr16 track lighting *by J***T on September 8, 2020* I have a 12v track lighting setup (gu5.3 mr16 bulbs) in a condo I recently purchased.
