This driver was a simple swap-out for the old transformer that was in place, which wouldn't work with the LED lamps. The unit is quite small, meaning that the terminals are also quite small and a little fiddly, but that doesn't detract too much from what is a good unit all-in-all. Time will tell on longevity of the device. Would probably purchase again should the need arise. Review: Fiddly to connect to cables - A nice compact unit which seems to work fine on 3 leds in a cabinet. However I did find it difficult to connect the cables. The connectors are small and slightly in an obstructed position. ## Features - Class II constant voltage LED driver, little dc transformer, AC 100-240V input, DC 12V 1.25A output, Maximum load 15 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.

The unit is quite small, meaning that the terminals are also quite small and a little fiddly, but that doesn't detract too much from what is a good unit all-in-all.

However I did find it difficult to connect the cables. The connectors are small and slightly in an obstructed position. ### ⭐⭐⭐⭐⭐ A great LED driver in a really good form factor *by A***R on 29 June 2025* A really good small unit that operates exactly as expected. The main benefit of this particular product is the size. It’s smaller than the competition that does exactly the same thing. That means I could get several of them into a singular waterproof enclosure outdoors. ## Frequently Bought Together - REYLAX 12V LED Driver 15W 1.25A, Power Supply Unit, 240V AC to 12V DC Transformer, Constant Voltage Driver Adapter, Low Voltage Transformers for DIY Light Strips, LED Bulbs and Ring Doorbell - 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.jp/products/265815363-12v-led-driver-15w-1-25a-power-supply-unit-240v](https://www.desertcart.jp/products/265815363-12v-led-driver-15w-1-25a-power-supply-unit-240v) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-18*
