How come LED Light Bulbs only last for about 2-3 Years?

I’ve bought and replaced a lot of light bulbs, and I noticed that all of them said “up to 20,000 hours” which would be about 5 years given 12 hours of daily use (which we definitely don’t).

    Since people are just giving snarky douchebag replies, I’ll actually attempt to answer the question since that’s what this community is for?

    The estimate given on the packages of these bulbs are absolute best case scenario, using an optimal temperature range and pattern of use that won’t really match up with the average household because:

    1. You may go on vacation and let your house get cold or hot. This could affect the life of thr bulb

    2. The manufacturer is likely leaving the bulbs on 24/7 when measuring. Most people turn lights on and off multiple times throughout the day. This can decrease the life of thr bulb, just like with any other electronic device.

    3. Humidity in the house can change dramatically year round. Manufacturing tests probably keep a constant humidity level.

    4. If you’re buying cheap random LED bulbs off Amazon from dogshit brands (i do thid too so not knocking you), the manufacturer estimates might just straight up be a lie.

    I’m sure there are other reasons but that’s a good start.
