They dont lie, but they do try to fool you.
The lamp is rated for 25,000 hours (so they say). That's under laboratory conditions.
The marketing department thinks that you and I cant figure out how long 25,000 hours is, so they turn it into something a little more relatable...like years. What the neglect to tell you is that it will only last 22 years if you only burn it 3 hours per night. If you have it on all night, it will only last about 8.5 years. If you live in Ecuador, the heat will probably kill it sooner than that. If you live in Alaska, it might last a little longer.
There's another marketing "fib" on there, as well. They claim that 3000 lumens is "nearly the same light" as 3600 lumens. That's a stretch. That's like saying that $80 is nearly the same as $100.
