Main Line vs Individual Step Leads: Which Stair-Light Kit Fits Your Staircase?
A stair-light kit should be chosen around the staircase you actually have: its turns, landing, finish access and the route you can still inspect later. “Main line” and “individual step leads” describe different product architectures; neither is a universal winner.
Start with the access plan, not a generic wiring diagram
Before comparing controls or colors, trace the route a kit would need to follow. Note the controller zone, first and last step, every landing or turn, and any place permanently closed after finishing. You are not designing an electrical circuit. You are deciding whether a manufacturer-defined system can be planned, fitted and serviced without guesses.
For fixed electrical work, local requirements apply. A qualified electrician should define the power-side work where required.
Three real MALIIGAZA approaches
STEP-09: a documented main-line route
STEP-09 uses a main line with separate step IC modules. Each light has an approximately 20 cm lead that connects to a nearby main-line node. This can fit when one edge route can be planned cleanly through the entire stair and its nodes remain serviceable. The main line and nodes should never be sealed behind a finish that cannot be opened later; individual modules can be replaced separately when access has been retained.
STEP-09 is a sequential stair-light system with remote control and daylight sensing, offered for 5–28 steps. It is not App-controlled. Its standard node spacing is 35 cm; a 40 cm version is a separately purchased option, not a default assumption.
STEP-P5: one planned lead allocation per step
STEP-P5 takes a different planning path. Every strip has its own 1–5 m extension lead that is screw-connected to the controller. Allocate an appropriate lead length to each intended step before installation and preserve that map. This suits a stair with clearly different route lengths when the homeowner also wants its verified App and RF remote access, timers, App-programmable always-on behavior, and individual step on/off.
Do not treat its leads as interchangeable after the fact or infer unlisted App features. STEP-P5 is offered for 5–16 steps.
STEP-07: short light leads plus product-defined extensions
STEP-07 gives each strip an approximately 30 cm Dupont lead, with 1–6 m extension leads supplied for the documented route. It can suit a stair where the equipment zone and each step’s reachable route have been confirmed in advance. Its relevant control differentiators are a wireless wall switch and dedicated always-on mode, not an App. The current product is offered for 5–20 steps.
Make the decision with one staircase drawing
| Question | What to check |
|---|---|
| Can the route stay accessible? | For STEP-09, retain service access to the main line and nodes. For STEP-P5 and STEP-07, preserve the individual lead map and equipment-zone access. |
| Where do lengths change? | Mark landings, turns, interrupted stringers and differing distances from the controller area before assigning a kit. |
| Which controls genuinely matter? | STEP-09: sequential main-line, remote and daylight sensing. STEP-P5: App/remote, timer and individual-step choices. STEP-07: wireless wall switch and always-on options. |
| What happens after the finish is closed? | Reject any plan that hides a required service point permanently or depends on an unverified extension, splice or substituted part. |
The goal is not to prove one architecture “easier.” A straight stair with one accessible edge may favor STEP-09. A project with deliberately mapped step-by-step distances may favor STEP-P5. A layout that benefits from the supplied STEP-07 extension approach and wall-switch option may favor STEP-07. The exact manual and physical staircase decide the fit.
Do not let the connection plan crowd out the lighting result
All three decisions should still leave room for an even, low-level guide light. MALIIGAZA COB strips create a continuous, dot-free line of light. An aluminum profile is not included with these stair-light kits and is not a prerequisite for the smooth COB effect. Treat any separate finishing detail as project-specific, not a required part of the system.
A practical final check
Use the product manual to label the equipment zone, each step, each landing and every point that must remain reachable. Then ask: if one section needs attention later, can you identify it without opening a finished stair blindly? If not, revise the route before buying or closing the finish.
FAQs
Is a main line the same thing as sequential lighting?
No. A main line describes a product connection architecture. Sequential lighting describes visual behavior. STEP-09 has both, but the terms are not interchangeable.
Is STEP-P5 automatically better for complicated stairs?
No. Its individual pre-attached lead allocation only helps when the route has been mapped carefully and its controls are a genuine fit.
Does COB stair lighting need an aluminum profile?
No. These kits do not include an aluminum profile, and COB strips already deliver a smooth, dot-free light line. A separate profile may be a finish choice for a specific project, not a requirement for even light.
Next step: draw the actual stair once, keep service points visible on the plan, and compare the current STEP-09, STEP-P5 and STEP-07 manuals against that same drawing.
