The module auto-senses and switches between leading-edge and trailing-edge dimming modes to match the connected load, supporting 10-150W incandescent and halogen lamps, 10-150W low-voltage halogen with electronic transformers, and 5-150W dimmable LED lamps.\u003c\/p\u003e\n\u003cp\u003eDesigned for two-way switching circuits where a single dimmer controls a lighting circuit that can also be switched from another location, the module fits a 25mm-wide grid aperture and requires a 35mm minimum back box depth. The push-on\/off mechanism and rotary knob provide direct control at the dimmer location, while a separate two-way switch elsewhere in the circuit can turn the load on or off without affecting the dimmed level set at the module.\u003c\/p\u003e\n\u003cp\u003eThe dimmer includes overload protection, over-temperature shutdown and an inrush current limiter to handle the surge draw from multiple lamps switching on simultaneously. Knightsbridge recommends a maximum of 10-12 lamps per dimmer to maintain stable performance and avoid exceeding the inrush protection threshold. The black nickel finish provides a dark metallic accent that pairs with both contemporary and industrial grid installations.\u003c\/p\u003e\n\u003cp\u003eThe module is a component for grid systems and requires a separate grid faceplate, sub-frame and back box (all sold separately). It does not function as a standalone dimmer without the supporting grid hardware.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e56.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e23 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.

Trailing-edge dimmers cut the rear of the waveform and suit electronic loads like dimmable LEDs and low-voltage transformers. This module auto-detects the load type and switches between modes automatically.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be used as a standalone dimmer?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The GDM150IBN is a grid module component that requires a separate Knightsbridge grid faceplate, grid sub-frame and back box to function. It does not include the cover plate or mounting hardware needed for installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 2-way mean in this context?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e2-way means the dimmer can be wired into a circuit with a second switch elsewhere that also controls the same lighting load. The second switch turns the lights on or off, while the dimmer module controls both on\/off and dimmed level at its own location.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is there a 10-12 lamp limit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMultiple lamps switching on simultaneously create a high inrush current as filaments heat or LED drivers charge. The dimmer's inrush current limiter protects the module from damage, but exceeding 10-12 lamps can trip the protection and cause unstable dimming. For larger installations, use multiple dimmer modules on separate circuits.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293679444235,"sku":"GDM150IBN","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1097372_327b16a3-2922-49ea-9291-ecc274e22073.jpg?v=1714662406","url":"https:\/\/niori.co.uk\/products\/2-way-10-150w-intelligent-dimmer-module-black-nickel","provider":"Niori","version":"1.0","type":"link"}
