Quick Answer: Upgrading to LED recessed lighting in a San Jose home costs $350-$900 to retrofit 6 existing incandescent can lights with LED trim and bulb kits (no rewiring needed), or $900-$2,500 to install 6 brand-new LED recessed lights with new wiring from a junction box (requires an electrical permit). For a full room (living room or kitchen with 6-12 lights), budget $800-$2,000 for retrofit or $1,800-$4,500 for new installation with wiring. Wafer-thin LED fixtures (e.g., Halo, Lithonia) don’t require a canister — they mount directly to the ceiling with a clip and are the fastest to install in existing ceilings with access. An electrical permit from San José Building Division is required for any new circuit or new wiring run — a permit is NOT required for a like-for-like retrofit (same wiring, new trim and driver).
