The T20-J integrates the 48V DC driver directly into the track's ceiling connection point, at 100W or 200W, so that no separate driver box is visible anywhere in the finished installation — the track appears to simply feed from a clean ceiling junction. Input 220-240V AC.

Sizing this correctly comes down to adding up the wattage of every fixture planned on that circuit before ordering. Eight T2012 12W spots total 96W — safely within the 100W supply. Ten of the same fixtures total 120W, which pushes past the 100W supply's capacity and requires either the 200W unit or a second circuit entirely. Getting this wrong in either direction has a real cost: undersizing means fixtures that won't run at full output or a supply running at its limit continuously, while oversizing is simply unnecessary spend on capacity the circuit will never use.

The in-built format is the right specification whenever the ceiling void at the track connection point has enough depth to house the integrated driver — which is the case in most standard Indian false-ceiling constructions. Where that void is too shallow, or where several circuits need to be fed from one centralised, more accessible location, the standalone 48V Stella supply is the alternative, connected to the track via a separate Input Module cable rather than living at the connection point itself.

One power supply serves exactly one circuit — it cannot be split across two separate track runs even if both are within its wattage capacity.

How do I work out whether I need the 100W or 200W supply?

Add the wattage of every fixture planned on that circuit. 100W total or under: the 100W supply. Over 100W but within 200W: the 200W supply. Beyond 200W: split the installation across two circuits, each with its own supply, rather than trying to overload a single unit.

When should I choose this over the standalone 48V Stella power supply?

Choose the T20-J In-Built when the ceiling void at the track's connection point has enough depth to house the driver, which covers most standard Indian false-ceiling installations. Choose the standalone 48V Stella when that void is too shallow, or when multiple circuits need to be fed from one centralised, more accessible location instead of a driver hidden individually at each connection point.

Beyond the wattage calculation itself, confirming the ceiling void depth at the intended connection point before ordering the in-built version specifically avoids discovering a fit issue after purchase — a quick measurement of available void space, compared against the driver's physical dimensions, settles whether in-built or standalone is the right call before committing to either.

What ceiling void depth does the in-built driver actually need?

Contact T21 via WhatsApp +91 94484 64040 with your false-ceiling void dimensions for exact clearance confirmation before ordering, since attempting to fit the in-built driver into insufficient void space is the most common reason to specify the standalone 48V Stella instead.
