Hello, I have am going through the HPS bulbs I have stored away and the majority of them have around this much use:![0105160227.jpg](/data/attachments/2678/2678139-fd062347d59ac4b18106d2e0ade8350b.jpg)
Some have burn marks on the bulbs, is it dangerous to use them? Does this effect lumens?
How much of the tube blackens before major effects to lumens?
I tried searching for forums on this but it pulls up a lot of different topics. Threw some tags on this thread.
I found bulbs that had little to no use and am going to use them to bud my current crop; but I would like to learn about judging bulb life.
Thanks for any input. Heading to my cold pillow and warm woman. Night all.
