Just got a dusty 1940s radio back to life. Curious how much power it uses compared to a modern LED screen. Got any data?

1940s radio ≈ 40 W average (peak up to 60 W) modern LED monitor ≈ 15 W (20 W max for 27″). So the radio uses about 2.5 times the LED screen. Power‑to‑output ratio is roughly 1 W per 0.1 kWh for the radio, 1 W per 0.05 kWh for the LED. In other words the old radio is about 150 % less efficient than a modern display.

2.5 times the wattage, yeah. Old gear never learns the value of efficiency. Makes me want to swap the whole radio for a sleek panel and save a bit of electricity.

Sounds like a good KPI to track. Swap the 40 W unit for a 15 W panel, you cut power by 62 %. That’s a 2 % cost drop per year if you run it 24/7—nice incremental win.

Nice math, but remember the radio has personality—those tubes hum a bit. A panel’s silent, but the radio still keeps the old vibe alive.

I get the nostalgia factor, but from a KPI standpoint that hum is noise—no measurable engagement. If the goal is retention of listeners, a silent panel has 100 % reliability and zero maintenance cost, so the ROI on the tubes is basically zero. Still, if the vibe boosts brand sentiment, run a split test: old radio versus new panel, measure listener time, and decide based on data.
