* 3000K: Warm, cozy – for hotels, residences, heritage, courtyards, tree lighting.

* 4000K: Natural, neutral – for modern buildings, plazas, parking lots, billboards.

* 5000–6500K: Bright, cool, alert – for sports venues, industrial sites, high-visibility areas.

Wattage dictates brightness and coverage.

* Select by application: Different scenarios require different power levels.

- 10W – 50W: Small courtyards, accent lighting, small billboards.

- 100W – 300W: Medium-sized plazas, parking lots, building facades.

- 500W+: Large stadiums, large-scale architectural floodlighting.

* Estimate by area: A rough rule of thumb:

- 10W: covers about 5–10 m² effectively.

- 50W: covers roughly 30 m².

- 100W: covers about 15 m² (with a 130° beam angle it can illuminate larger areas).

- 160W: can meet lighting needs for about 30–40 m².

Size matters for installation.

* Verify mounting space: Make sure the chosen fixture fits into the reserved location without interfering with other structures.

* Assess load capacity: Higher-wattage units are usually heavier; confirm that the wall, bracket, or support can bear the weight.
