Yes, I think they are counting on the consumer not even knowing what a "lumen" is. Those 450 lumen bulbs would be great for a reading lamp or something, I suppose, but not for overhead lighting.

I have a chart which I'll replicate here. The standard lumens ratings come from Wikipedia. I've also (arbitrarily) created a range column which shows a + / - 10% variance of what I would expect to see. I'm using dashes for spacing to try to maintain column alignment. Watts ----- Lumens ----- -10% Lumens ----- + 10% Lumens 5 ---------- 25 ------------ 23 ----------------- 28 15 --------- 110 ----------- 99 ----------------- 121 25 --------- 200 ----------- 180 ---------------- 220 40 --------- 500 ----------- 450 ---------------- 550 60 --------- 850 ----------- 765 ---------------- 935 75 --------- 1200 --------- 1080 --------------- 1320 100 -------- 1700 --------- 1530 --------------- 1870 150 -------- 2850 --------- 2565 --------------- 3135 You really have to watch out. There's a lot of ... er ... horsefeathers out there and what I consider to be fraudulent advertising. GE now has a "60 W replacement" with SUBSTANTIALLY less lumens than a regular 60 W bulb and very bad life expectancy. There are also some "long life" light bulbs I saw at Walmart that have maybe double the life of normal, but no where near the 10,000 hours of the heavy duty bulbs that Allen (I think) posted about before. PS. I recently got a 75 W equivalent 1100 lumen Cree from Home Depot. I wrote about it in another post. I like it, and it seems to be doing its job. I just noticed that the lumen rating is just barely within my spec range for a "75 W" bulb. But, it's enough. It wasn't cheap though, at $ 22.
