@peachfuzz or anyone who has found a good rule of thumb for the life expectancy of lights-
so I run a 600 wt MH/HPS - I Use T5 on my seedlings they really love this a lot and then when they outgrow my seedling space usually by 4 weeks and praying there is no one in the tent flowering lol I then move them into the tent with the 600 MH going at 18/6 for at least a month or so to fill up the scrog fully then I switch to 12/12 for 4 weeks then HPS to finish the last 4/5 weeks of flower. How long before i need to buy new lights? looks like the MH gets about 4 weeks of 18 on daily and 4 weeks of 12 on daily and the HPS gets 4/6 weeks of 12 on daily- T5s get 4/6 weeks 18 on daily -
So how many runs like this until i replace everything?
