BG Nexus NBN81 200W Trailing Edge LED Dimmer Switch – 1 Gang 2 Way, 100W LED - Black Nickel

BG Nexus Metal NBN81-01 Black Nickel 200W Trailing Edge LED Dimmer Switch

Create smooth, adjustable lighting with the BG Nexus Metal NBN81-01 Black Nickel Intelligent Trailing Edge Dimmer Switch.

Designed for modern dimmable LED lighting as well as compatible CFL, halogen and incandescent lamps, this premium single / 1-gang dimmer switch combines a 200W maximum traditional-lighting rating, 100W dimmable LED capacity, 2-way switching capability and rotary dimming with push on/off control.

Finished in Black Nickel, the NBN81-01 is particularly suited to customers looking for a decorative alternative to conventional white dimmer switches while retaining practical features such as soft start, overload protection and silent dimming.

200W Trailing Edge Dimmer – Up to 100W LED

BG markets NBN81-01 as a 200W trailing-edge dimmer with a 100W LED rating.

The official Nexus Metal technical sheet gives the individual module load ranges as:

• Dimmable LED: 5–100W
• Tungsten / Incandescent: 5–200W
• Halogen: 20–200W
• Dimmable CFL: 5–100W

This makes the product highly relevant for searches including:

• 100W LED dimmer switch
• 200W dimmer switch
• trailing edge LED dimmer
• Black Nickel LED dimmer switch
• low wattage LED dimmer
• dimmable LED wall switch
• electronic light dimmer

Only dimmable lamps that are compatible with the dimmer and remain within the specified load range should be used.

Intelligent Trailing Edge Dimming

NBN81-01 uses trailing-edge dimming technology, sometimes also called lagging-edge dimming. BG specifically positions this type of dimmer as offering a lower minimum load than traditional leading-edge designs and greater compatibility with LED, halogen, CFL and incandescent lighting.

This gives the product strong search relevance for customers replacing older dimmers that may not operate modern low-wattage LED lamps effectively.

Designed for Dimmable LED Lighting

For LED installations, BG specifies a load range of 5–100W per dimmer module. Its installation manual also states a maximum of 10 dimmable LED lamps on the single-dimmer configuration, subject to the total electrical load and lamp compatibility.

This is an important distinction: 100W is the total rated LED load, not the rating of each lamp.

For example, the actual number of LED lamps that can be connected depends on their wattage, driver characteristics and compatibility with trailing-edge dimming.

Rotary Light-Level Control with Push On/Off

The NBN81-01 combines rotary dimming control with push on/off operation. BG describes the unit as a rotary dimmer with a push function, allowing the knob to perform two jobs:

• Rotate to adjust the light level
• Push to switch the connected lighting on or off

This combination is particularly useful for customers searching for:

• push dimmer switch
• rotary LED dimmer
• push on off dimmer switch
• Black Nickel rotary dimmer
• adjustable wall light dimmer

2-Way Switching Capability

BG specifies NBN81-01 as a 2-way dimmer switch.

This allows the lighting circuit to be incorporated into an appropriate two-way arrangement where the same light needs to be switched from two positions.

A particularly important installation rule appears in BG’s official instruction manual:

Only one dimmer is allowed in a two-way circuit.

The second switching location therefore uses an appropriate 2-way plate switch, rather than another NBN81-01 dimmer.

This makes the product useful for suitable lighting arrangements in areas such as:

• Bedrooms
• Living rooms
• Dining rooms
• Hallways
• Staircases
• Landings
• Rooms with two entrances

Can Also Be Used for 1-Way Switching

Although NBN81-01 is a 2-way switch, BG’s instructions confirm that a 2-way switch can also be wired for a 1-way application using the appropriate terminals.

This gives customers flexibility where only one wall position is needed to control and dim the lighting.

Soft-Start Lighting

BG incorporates a soft-start function.

The technical literature states that the lights rise to their set level over approximately one second rather than switching immediately to full output, while the installation manual specifies approximately 1.2 seconds from 0 to 100%.

BG states that this feature is designed to help prolong lamp life.

Built-In Overload Protection

The intelligent electronic circuit incorporates overload protection.

If an excessive lighting or transformer load is connected, BG states that the dimmer can reduce or switch off the output until the overload condition is corrected, rather than simply continuing to operate under the excessive load.

This does not remove the requirement to calculate and remain within the specified load rating when designing the lighting circuit.
