# 200W Floodlights

200 W belongs on poles above 8 m, over yards and loading areas. Two figures matter at this size: thermal design and total weight. At the same wattage an extruded aluminium body and a die-cast one can differ by 2 kg, and wind load at the pole head is calculated from that weight.

## [Key parameters](https://www.xingguanglightingcn.com/en/glossary#efficacy)

| Power | 200 W |
| --- | --- |
| Efficacy | 125 lm/W |
| Luminous flux | 25,000 lm |
| Maintained flux | 17,500 lm |
| Mounting height | 8–12 m |
| Coverage per fixture | 200–320 m² |
| Design illuminance | 50–100 lx |
| HID equivalent | 400 W |

## What the wattage figure does not tell you

At 125 lm/W, 200 W gives about 25,000 lm at the fixture; applying a 0.7 maintenance factor, roughly 17,500 lm reaches the floor at end of life. Layout counts come from 17,500 lm, not from the nameplate 200 W — layout by wattage and the far row always ends up dim.

A second double count: the 125 lm/W figure already includes driver losses. Discounting again by driver efficiency deducts the same loss twice and over-counts fixtures.

## The height and area it actually covers

At 8–12 m and a design illuminance of 50–100 lx, one 200 W fixture covers about 200–320 m². That range is back-calculated from the maintained 17,500 lm, not the initial output — lay out on initial [lumens](https://www.xingguanglightingcn.com/en/glossary#lumen) and the site is under-lit well before the first relamping cycle.

If the existing HID is 400 W, 200 W lands in the same bracket: comparable flux, roughly a third of the power draw, and the circuit and switchgear usually carry over. What to re-check is inrush current and the earth-leakage setting.

## Four things to verify before ordering

① Whether flux and efficacy are quoted for the complete fixture or the light source — a 10–15% difference that changes the fixture count. ② Whether colour temperature and CRI are measured or nominal values; mixed CCT within one batch is the most common arrival dispute. ③ Driver brand and model, plus its derating curve at high temperature — it is the only part that really sets life. ④ The mounting kit list: chain, bracket and anchors in the box, or the site stops for a day.
