Let me explain it to you.
Yes, you can choose some mutually exclusive parameters. But also you can not choose anything, it is not neccesarry. Anyway I will send payment bill manually.
About letter on the end. What is it mean was in the rus language in price
Bronse - it was 2 years ago, I delete it, but in english version it can be as I see. I just fix it in 6w model. It mean how much leds will in lamp, for example in 12w led bulb can be 25w led, it will more effective.
6 - wattage. It is real, not fake like chinawatts
- bigger body
d - dimmable
x - eXperimental (tried to do cheaper)
s - switchable spectrums
for example on lamptest was 12D Titanium (platinum)
d - China sunlike (SOL)
D - Seoulsemico (SAW)
Now more leds is marked like 13D+ or 13D. Only on bodies.
this was 2 years ago. see model: 12D titan. it is w/o cover (diffuser) and with it
100lm per 1w from the line. 15% take off cover (diffuser)
