Enter your LED strip type and length to get total wattage, current draw, recommended power supply size and safe wiring guidance. Based on real ArrayStar factory specs (SMD 2835 / COB 480).
Results are engineering estimates for planning. Final spec depends on exact product, CRI and dimmer type — ask us to confirm your configuration.
Our engineers reply within 12 hours with confirmed W/m, driver selection and FOB price.

As a rule of thumb: 12V strips over 5 m, 24V strips over 10 m and 48V strips over 15 m should be fed from both ends (parallel runs) to avoid visible brightness drop at the far end. ArrayStar recommends planning the feed layout before install.
Power per meter varies with CRI (90+ / 95+ / 98+) and CCT. High-CRI COB strips can draw 10–20% more than the base spec. Check the datasheet of the exact SKU or ask us to confirm your batch's real W/m.
Yes, if total wattage stays within the driver's rated power and you respect the parallel rule. Keep 20% headroom and use the correct wire gauge for the total current.
| Typical run (24V) | Recommended feed | ArrayStar SKU example |
|---|---|---|
| Up to 10 m | Single end feed, 2×1.0 mm² wire | COB 480LED/m 8/10 mm |
| 10–20 m | Feed from both ends (parallel) | SMD 2835 120LED/m 10 mm |
| Over 20 m | Parallel + separate drivers per zone | Ask our engineers |
