SaveMyLight are the only UK retailer of replacement Hytec lighting transformers. Hytec have really upped their game over the last year. Having visited their new factory in Guangdong and seen their process for manufacture and Quality Control it is a pleasure to sell their products. The HY-2350A is suitable for controlling high & low voltage halogen floor lamps. This product cannot be used with LED bulbs. The HY-2350A is the only product on the market that can replace the Kaoyi KHT234H, which has been discontinued. Although a slightly smaller unit the two on / off adjuster knobs are located in the same place as the KHT234H. The HY-2350A can also be used to replace the Yongzan Electron BT360-XL (FL-7699G) twin dimmer. The attached circuit diagram is only for the units we sell which are a revision 3.0 model. Using this diagram to install past revisions sold by other companies will damage your unit.
