Green Tree Osram Lumilux L18W/835 Fluorescent Tube

A very big thanks goes to Liam who was generous enough to give me two of these tubes as gifts! I value that so super much because I wanted to have this color from Osram Lumilux for such a long time, and now I have it! Such a nice and soft color, I always found the green tree Osram Lumilux tubes to be very washed out, and this 835 looks almost identical to 840, I can only detect a slight difference between the two, while HGE 835 differs quite a lot from 840. HGEs 835 is more like a butter color while Osram 835 is plain whitish banana like all 840 are in mu opinion. All in all, just amazing tubes and I am so grateful to have these! Now I wonder did Osram green tree Lumilux ever made a 850? Would be so amazing to collect the 18w range in all five colors 865 840 835 830 & 827. So far I only have 840 and 835. In 36w I have 830 and 840 and in 30w form I have 865.
