Review: Great replacement driver - Bought this to replace a driver for a led strip light which had fiailed after about 10 years. Good price and arrived next day. Easy, if a little fiddly to connect ac supply and dc load. Worked first time. Hope it lasts! Review: Amazing product! - It’s easy to install, works well with leds. Small size should fis well inside most existing components. ## Features - Class II constant voltage LED driver, little dc transformer, AC 100-240V input, DC 12V 2.5A output, Maximum load 30 watts, 50/60Hz. - Advanced circuit boards and electronic components provide with perfect over current, over voltage, thermal overload and short circuit protection built in. - Easy to install and wire up. No humming, light flicker or switch on delay from the transformer. Low power design, static power consumption. - The transformer's compact size allows it to be installed in tight spaces, such as behind kitchen cabinets, furniture walls, or bathroom mirrors. - Upgrade your lighting system, replace your old halogen bulbs with the constant voltage LED transformer and save on energy costs, which is an ideal choice for various lighting applications, including LED spotlights, strips, and lamps. - WARM TIPS - To optimise efficiency and performance, ensure that the load remains below 80% of the maximum capacity of the 12V 30W transformer. - COMPATIBILITY - Please note that our LED driver 12v dc is specifically designed for constant voltage power supplies. It is not compatible with dimmable or colour changing lighting products such as dimmable LED lights or colour changing light bars. - Trusted Brand Guarantee - Experience exceptional customer service with our dedicated 24/7 support team. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08P21WJ33 | | Best Sellers Rank | 653 in Lighting ( See Top 100 in Lighting ) 3 in Low-Voltage Transformers | | Brand | REYLAX | | Country Of Origin | China | | Current Rating | 2.5 Amps | | Current rating | 2.5 Amps | | Customer Reviews | 4.4 out of 5 stars 1,748 Reviews | | Included Components | LED Driver 12V 30W | | Item Dimensions D x W x H | 94D x 43W x 23H millimetres | | Item Weight | 80 Grams | | Manufacturer | REYLAX | | Manufacturer Part Number | DT-NS12V-30W | | Maximum Frequency | 60 Hz | | Minimum Frequency | 50 Hz | | Model Number | DT-NS12V-30W | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Power Source | DC | | Power source | DC | | Product dimensions | 94D x 43W x 23H millimetres | | Specification Met | CE, RoHS, UKCA | | Specification met | CE, RoHS, UKCA | ## Product Details - **Brand:** REYLAX - **Current rating:** 2.5 Amps - **Mounting type:** Surface Mount - **Power source:** DC - **Product dimensions:** 94D x 43W x 23H millimetres ## Images ![LED Driver 12V 30W, Transformer 240 to 12V DC 2.5A, Constant Voltage Power Supply Adapter, Low Voltage Converter for Strip Light, Downlight and G4, MR11, MR16 Light Bulb - Image 1](https://m.media-amazon.com/images/I/61xPq+XEWkL.jpg) ![LED Driver 12V 30W, Transformer 240 to 12V DC 2.5A, Constant Voltage Power Supply Adapter, Low Voltage Converter for Strip Light, Downlight and G4, MR11, MR16 Light Bulb - Image 2](https://m.media-amazon.com/images/I/7139DHMwflL.jpg) ![LED Driver 12V 30W, Transformer 240 to 12V DC 2.5A, Constant Voltage Power Supply Adapter, Low Voltage Converter for Strip Light, Downlight and G4, MR11, MR16 Light Bulb - Image 3](https://m.media-amazon.com/images/I/71NTiOqaysL.jpg) ![LED Driver 12V 30W, Transformer 240 to 12V DC 2.5A, Constant Voltage Power Supply Adapter, Low Voltage Converter for Strip Light, Downlight and G4, MR11, MR16 Light Bulb - Image 4](https://m.media-amazon.com/images/I/71zOOOSXWsL.jpg) ![LED Driver 12V 30W, Transformer 240 to 12V DC 2.5A, Constant Voltage Power Supply Adapter, Low Voltage Converter for Strip Light, Downlight and G4, MR11, MR16 Light Bulb - Image 5](https://m.media-amazon.com/images/I/71j9MPKTTzL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What are the dimensions of this led driver?** A: The dimensions are 95 mm × 44.5 mm × 24mm(3.74 inch × 1.75 inch × 0.95 inch).

Good price and arrived next day. Easy, if a little fiddly to connect ac supply and dc load. Worked first time. Hope it lasts! ### ⭐⭐⭐⭐⭐ Amazing product! *by S***T on 19 January 2025* It’s easy to install, works well with leds. Small size should fis well inside most existing components. ### ⭐⭐⭐⭐ Does the job, good value, but fiddly cable connection *by P***S on 25 February 2022* Used the 15W and 30W versions of this to replace fluorescent under-cupboard lights in the kitchen. Seemed good value and does the job, barely gets warm and only a very slight buzz/whine - inaudible in any normal conditions. Only complaint is the screw terminals are set down below the cable entry which makes inserting cables quite difficult. They seem to be designed for stranded, but stranded cable mushes up rather than pushing into the terminal. I ended up crimping on bootlace ferules, then trimming and bending slightly. ## Frequently Bought Together - REYLAX LED Driver 12V 30W, LED Transformer 240 to 12V DC 2.5A, Constant Voltage LED Power Supply Adapter, Low Voltage Transformer Converter for Strip Light, Downlight and G4, MR11, MR16 LED Light Bulb - 3528 2835 2 Pin 8mm LED Strip Connector - DIY Strip to Wire Quick Solderless Connection for 12v 24v Single Color Led Strip Lights (Pack of 10) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/266215266-led-driver-12v-30w-transformer-240-to-12v-dc-2](https://www.desertcart.co.th/products/266215266-led-driver-12v-30w-transformer-240-to-12v-dc-2) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-06-06*
