Reversing that order is what causes the expensive mistakes — a luminaire that cannot be fitted to the rail that was already installed, or a beam that was chosen before anyone knew the mounting height. ## The order matters more than the choice Most specification errors in track lighting come from choosing the luminaire first. The luminaire is the visible part and the easiest to get enthusiastic about, but it is also the most reversible: it can be swapped later without touching the building. The rail cannot. 1. **Rail platform** — single-circuit or three-circuit, and which supply arrangement. 2. **Profile and mounting** — surface, recessed or suspended, and the finish. 3. **Adapter interface** — confirmed against the rail, not assumed. 4. **Luminaire** — power, output, beam, colour, size. 5. **Control** — switching groups, and DALI where control wiring is required. ## Fix the rail platform first The rail decision is driven by how many switched groups the space needs and how long the runs are. A single-circuit rail switches everything on it as one group; a three-circuit rail puts luminaires on the same rail into up to three groups and distributes the load across three conductors. The [single-circuit versus three-circuit guide](/resources/single-circuit-vs-three-circuit-track-rails/) works through that choice, and the [supermarket comparison](/resources/supermarket-track-lighting-china-vs-europe/) covers the electrical consequences for long runs. Mounting method is a separate decision inside the same platform: surface, recessed and suspended versions use their own matched component ranges, so keep each mounting method on its own line of the project list. ## Confirm the adapter, not the assumption The adapter is where cross-supplier projects fail. Rail cross-section, conductor position and adapter geometry differ between standards, and a luminaire that physically clips into a rail is not proof of electrical compatibility. Confirm the rail, adapter and luminaire as one system against the current drawing, and where the project permits, against an approved sample. ## Then compare the luminaires Once the platform is fixed, the luminaire comparison is straightforward — and it should be made on more than beam angle. The HAOTAI finished range is the TL01–TL05 series: sixteen sizes from 12 W to 40 W, CRI 90, 2700 K / 3000 K / 4000 K, IP20 for indoor use. | Series | Format | Sizes | Beam | Typical role | |---|---|---|---|---| | TL01 | Adjustable spotlight | 12 W / 20 W / 25 W / 30 W / 40 W, Ø50–Ø90 mm | 24° / 36° | general retail accent, from compact to high output | | TL02 | Adjustable spotlight | 15 W / 25 W / 35 W, Ø65–Ø85 mm | 24° / 36° | mid-size accent and feature lighting | | TL03 | Compact spotlight | 20 W / 30 W / 40 W, Ø80–Ø100 mm | 24° / 36° | shallow ceilings and low-profile ceilings | | TL04 | Zoomable | 15 W / 25 W, Ø80 / Ø100 mm | 20°–55° zoom | displays that change, tight-to-wide framing | | TL05 | Zoomable | 15 W / 25 W / 35 W, Ø65–Ø85 mm | 15°–55° zoom | flexible accent where the beam is set on site | Confirm the exact model, colour temperature, beam option and finish for the current configuration before quotation. ## Choosing on the site, not in the catalogue | Requirement | What to specify | Why | |---|---|---| | Highlighting merchandise at close range | Narrow fixed beam, higher output | A tight beam at low mounting height delivers punch without over-lighting | | Even washing of a wall or shelf run | Wider beam, careful spacing | Beam angle and spacing work together; uneven spacing reads as uneven light | | A layout that will change | Zoomable optic | The beam is set on site rather than re-specified | | Low or exposed ceilings | Compact body, controlled cut-off | Aperture and glare control matter more than raw output | | Several scenes from one line | Three-circuit rail | Groups come from the rail, not from extra cabling | | High ceilings with long throws | Higher output, narrower beam | Output has to survive the distance | Two specifications that are often treated as afterthoughts deserve equal weight: **aiming range** (how far the head rotates and tilts determines whether the light can actually reach the merchandise) and **glare control** (at low mounting heights an uncontrolled beam is visible to shoppers and reads as an installation fault). ## What to send with a technical enquiry Send the rail platform and profile standard, the mounting method, the rail lengths, the finish, the required adapters and accessories, the target market, and the expected quantity. With those, the correct current drawing package can be issued — and the answer to "will this fit?" comes from a document. The [buyer FAQ](/faq/) lists the questions that most often come back from specification teams. ## Frequently asked questions ### Should I choose the luminaire or the rail first? The rail. The luminaire can be replaced later without building work; the rail and its feeds cannot. Fix the platform, then the adapter, then the luminaire. ### Is a wider beam always the safer choice? No. A wide beam spreads less light on the target and produces more spill and glare, which is visible in a low-ceilinged store. Match beam angle to mounting height and to the size of the object being lit. ### What CRI do I need for retail? The TL01–TL05 range is supplied at CRI 90, which is appropriate for merchandise where colour accuracy matters. Confirm the requirement against the goods being displayed. ### Can I use the same luminaire on single-circuit and three-circuit rails? Only if the adapter is matched to that specific rail. The luminaire head may be common to a series, but the adapter interface belongs to the rail standard. ### How many luminaires can one rail carry? The limit is set by the rail's rating, the per-circuit current and the voltage drop over the run — not by a fixed luminaire count. Have it calculated rather than estimated.
