How to choose the right strip-light driver
Step 1 — Voltage: Check what your LED strip needs. Most consumer strips are 12V; longer / brighter strips are often 24V. The driver output voltage must match the strip's voltage exactly.
Step 2 — Wattage: Multiply strip wattage-per-metre by total length, then add 20% safety margin. Example: 14.4W/m × 3 metres × 1.2 = 52W → 60W driver (SP-727 or SP-852). Don't run a driver at 100% of rated wattage continuously.
Step 3 — IP rating: Indoor installations (cove, cabinet, false ceiling) can use IP20 drivers — SP-852. Outdoor or damp-area installations (signboard, façade, balcony) need IP67 — SP-727. The driver housing matters as much as the strip's own waterproofing.
Step 4 — Dimming (optional): If you want dimming, order the TRIAC-dimmable variant. Standard non-dimmable drivers won't work with wall dimmers — the dimmer must be matched to the driver's input topology.
Step 5 — Brand & warranty: Cheap unbranded strip drivers fail within 6-12 months in Indian conditions (heat, voltage swings). Branded drivers with proper potting and Indian-grade components last 3-5+ years. Smooth Power drivers carry a 2-year warranty.
