I bought two 2ft agrobright t-12 5200k bulbs awhile back to put into a fixture i had pulled from my house and saved. My question is how can i tell how many watts these are? Are all two feet t-12's the same? Appreciate any help i am running 12-12fs and want to start putting my seedlings under these then move to a 400 after a week or so.
