我把公寓里的每个灯都换成了可寻址的LED灯带。
多年来,我一直讨厌我租房里的顶灯——那种让一切看起来像办公室的刺眼5000K灯具。最终,我把它们拆掉,换上了WS2812B LED灯带。总花费:180美元,工作两天,墙上没有任何孔。
我做了什么:
• 42米的60 LEDs/m WS2812B(5V,从AliExpress购买,价格为每米3.8美元)
• 3个5V 40A电源(每个22美元),隐藏在衣柜里
• 一台运行WLED的ESP32(刷机只花了3分钟)
• Home Assistant集成,用于昼夜节律照明和运动触发
• 扩散器:12美元的宜家LACK架子 + 当地五金店的半透明亚克力
令人惊讶的数据:
在全白模式下的实际功耗:整个公寓180瓦(用Kill-A-Watt测量)
这还低于我拆掉的三只60瓦等效灯泡的功耗。
按每千瓦时12美分计算,每年的费用约为30美元,即使我24小时开着它们。
最大的教训是:扩散器比LED灯更重要。没有它们,效果就像一台游戏电脑爆炸了一样。

For years I hated the overhead lights in my rental – harsh 5000K ceiling fixtures that made everything look like an office. I finally ripped them out and replaced every light source with WS2812B LED strips. Total cost: $180, 2 days of work, zero holes in walls.<p>What I did
• 42 meters of 60 LEDs/m WS2812B (5 V, bought from AliExpress for $3.8/m)
• 3 × 5 V 40 A power supplies ($22 each) hidden in closets
• One ESP32 running WLED (took 3 minutes to flash)
• Home Assistant integration for circadian lighting + motion triggers
• Diffusers: $12 IKEA LACK shelf + transluscent acrylic from local hardware store<p>Surprising numbers
Real power draw at full white: 180 W for the entire apartment (measured with Kill-A-Watt)
That’s less than the three 60 W-equivalent bulbs I removed.
Cost per year at 12 ¢/kWh: ~$30 even if I leave them on 24/7.<p>Biggest lesson: diffusers matter more than the LEDs. Without them it looks like a gaming PC exploded.
