so I just bought a lamp with an integrated LED array and it doesn't ever need replacing, no bulbs, projected lifetime 30+ years. I bought it from my workstation. It will arrive at my home tomorrow morning. For just a moment there I'm really enjoying living in the future.
even my best compact fluorescents have never lasted more than about 18 months. if this advertises 20+ years and only gets 5 years it's still a massive upgrade.
