I dislike anything above 3500k or so.

Sell bulbs at first as “100 watt eq. – 1,600 lumens)

After a year or so, sell bulbs as 1,600 lumen – 100 watt eq. with the “100 …”  in smaller script.

People will catch on.

What also could be helpful is to sell as 16 hundred lumen.  People would find it easier to shop for a 3, 8, 16 than for a 3,000, ….

Oh, and why don’t you buy some ad space and support the site rather than trying to sneak some for free?

Incandescent filaments evaporate over time and the tungsten particles collect on the bulb wall. This typically results in 10-15% depreciation compared to initial lumen output over the 1,000 hour life of an incandescent lamp.”

Led and fluorescent drop off fairly quickly so buy MORE lumens than you need. I would suggest 20% more.

Then next step down is 4100k and that will provide a warmer color

What color temperature in the white range would not have the blue tint.
