what kind of light is this?

[Wrebbitrocks]

hey!

its starting to cool down again and i dont want to leave my plants outside. ive tried many methods of growing plants and lost many. so im going to have a go at lights.
but before i fork over a paycheck, i want to know how to work things. ive seen some great success and would like a go at it

heres what i have: my brother had this thing laying around and i want to see if its good enough for plants. it has two fixtures with 2 bulbs about 2.5ft in length.
i have one of those 2prong moisture/ph/light meters and i put it right above the leaves of the plants which were maybe 2 inches below the bulbs and the meter didnt even move. i thought it was broken but it work just fine and measured 1500 at my bathroom window. i know that cant be good but it has to be using SOME fc's if its light. ive read that plants dont need many if theyre always under a constant spectrum or whatever. its too early to tell now but while the temps outside rise again, the plants will have to deal with it til spring.

can you guys help me identify what this fixture is and what kind of bulb it is? idk what this whole t5 t8 etc stuff is nor what fixtures you need. thanks for the help
