5 watts led equivalent to 100 watts incandescent... Someting's grwong.

This is a 490lm lamp, and a 40w incandescent have 415lm, it's equivalent to 50w, no to 100w!

It says "Lamp bead:2835" dollars? KWh? Euros?
I bought this lamp just for an explaple of LED lamp, because the LED's are visible.

"Lamp bead:2835" Is likely the LED chip type/size.

Old lighting is, and will always be, the best lighting.

They doing this on purpose, in order to get high lumen efficacy figures. The only way to measure actual lumens, is by using an integrating sphere: https://en.wikipedia.org/wiki/Integrating_sphere

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).
