The H1 Pro has a wider fixture selection — pendants, polarized wall-washers, and tiltable grilles aren’t available on V1 — and is priced lower across the board (V1 is roughly 50% more on most fixtures and drivers). Both run on 48V DC with Zigbee 3.0, share the same 2700K–6000K range, and require an Aqara hub. Choose V1 for the slim look, fixture finishes and brighter output; choose H1 Pro for fixture variety and value.
The V1 is Aqara’s newer ultra-slim magnetic track — its 7.2mm surface profile is much less visible on the ceiling, fixtures come in white or black (vs H1 Pro’s white only), and the lights are slightly brighter. V1 also has a dedicated IoT Adapter that lets you clip Aqara sensors and cameras directly onto the track.
