200W is a huge number for modern lights.
You don't care about the power consumption, You care about the light level produced (Watts != Lumen).
Most advice says 500 to 1000 lux is fine for an office desk (en 12464).
For a 1 sq meter desk, that's about 800 lumens worth of light, or maybe 50 watts max in modern LED lighting (two 800 lumen bulbs, 14W each).
LEDs are just way better than older lights.
- NewJazz 1y agoI'm sitting staring at an 8W filament led Edison bulb, 800 lumens. For a zigbee bulb I found, 11W, 1100 lumens. And I think they include ZigBee overhead in their 11W? Don't even need PoE+ for that. It would just come down to chip and maybe power cost difference between Ethernet with PoE vs wireless with traditional 120V electrical wiring. Pretty pointless to retrofit I'd think, but for new construction it could be viable.
