| Track and fixture compatibility | Confirm the track voltage, connector type, polarity, mechanical fit, and supported fixture families. Check whether components from different systems can be mixed. | All track, power supplies, connectors, and luminaires should be explicitly listed as compatible within the same system. Do not assume magnetic tracks are interchangeable. | Magnetic attachment alone does not guarantee electrical or mechanical compatibility. | 20% |
| Light output and efficacy | Compare delivered lumens and lumens per watt for each fixture, not just LED-chip wattage. Check photometric files when available. | For general comparison, look for published fixture-level efficacy around 80–100 lm/W or higher, while matching lumen output to the intended task and beam angle. | Higher wattage does not necessarily mean more useful light; optics and thermal design affect delivered output. | 15% |
| Color quality | Review correlated color temperature (CCT), color rendering index (CRI), and, if provided, TM-30 data. | Choose a CCT suited to the space; 2700–3000 K is commonly used for warmer residential settings, while 3500–4000 K is often selected for more neutral spaces. CRI 90+ is a useful target where color appearance matters. | CCT affects perceived warmth, while color rendering affects how surfaces, materials, and products appear. | 12% |
| Beam control and visual comfort | Check available beam angles, shielding, glare control, and whether the distribution suits accent, task, or ambient lighting. | Compare documented beam angles and IES/LDT photometric files where available; assess glare in the actual viewing positions and mounting heights. | A high lumen figure alone cannot show whether light is aimed effectively or causes uncomfortable glare. | 12% |
| Dimming and controls | Verify dimmer or control protocol compatibility, minimum dimming level, smoothness, and whether flicker data is published. | Require documented compatibility with the intended control system and test the complete driver–fixture–dimmer combination before installation. | A fixture may be dimmable but still perform poorly with an incompatible control or driver. | 10% |
| Electrical safety and installation | Check rated input, power-supply capacity, wiring instructions, grounding requirements, and applicable electrical safety approvals for the installation location. | Use products with recognized certification applicable in the project jurisdiction; have mains-voltage installation completed in accordance with local electrical codes by a qualified professional. | The track system includes electrical components and must be installed and loaded within its ratings. | 12% |
| Thermal performance and service life | Review rated ambient temperature, thermal management, lumen-maintenance data, and the stated conditions behind lifetime claims. | Prefer documented lifetime and lumen-maintenance figures with a stated test basis; compare like-for-like data rather than relying on an unsupported lifetime number. | LED life and light output depend on operating temperature, driver quality, and use conditions. | 8% |
| Environmental suitability | Check the fixture’s ingress protection (IP) rating and stated suitability for the room’s moisture, dust, and temperature conditions. | Use only a rating appropriate to the location and local requirements; do not assume an indoor magnetic track fixture is suitable for wet areas. | Environmental protection varies by fixture and is not guaranteed by the track system itself. | 5% |
| Modularity and future changes | Assess the range of compatible spotlights, linear modules, pendants, track lengths, connectors, and replacement parts. | Favor a documented, expandable system that offers the fixture types and replacement components required for the planned layout. | A broad compatible range can make it easier to adjust lighting without replacing the whole installation. | 6% |
