# What’s the difference between the PIXIE SDD300BTAM and the SDD400SFI

# Introduction

Both the SDD300BTAM and the SDD400SFI work with the PIXIE smart home system.

 

## SDD300BTAM

The SDD300BTAM is a Generation 3 (G3) dimmer in a compact form factor for up to 6 gang dimmer wall plates, with the ability to adjust fade rates and select LED indicators status based on the dimmers state. This is an upgrade to the G2 version of the dimmer the SDD350BT.

## SDD400SFI

The SDD400SFI whilst also fully compatible with the PIXIE ecosystem, requires **additional and specific** lighting products to operate.

It is 1 part of a system designed to eliminate flickering LED downlights based on the off-peak hot water tones electricity companies inject into the electrical supply in NSW and parts of South East Queensland.
