Expose the arithmetic, respect the hardware limits

LED Power Estimator

Estimate watts and current from strip length, advertised watts per foot, voltage, segments, and planning headroom.

Planning result

49.2 W estimated strip load · 59 W with headroom

At 24 V, the planned wattage corresponds to about 2.46 A in arithmetic terms.

Base estimate: 16.4 ft × 3 W/ft
Planning headroom: 20%
Segments: 1; each route and connector still needs a supported plan
Voltage: 24 V must match the strip exactly

Verify before acting

This does not size wire, connectors, fuses, injection points, adapters, or enclosure ventilation.
Use manufacturer-approved components; permanent wiring requires a qualified electrician.

01

Enter the room, route, or product claim

Inputs remain visible so you can challenge the assumptions.

02

Use the range as a shortlist

The result narrows questions; it does not certify a product or room.

03

Measure and verify

Check the real space, documentation, safety limits, and seller before purchase or installation.
