It might peak at 40 watts but will not run continuous at 40 watts. I would think that we have seen enough false claims to not take the MFG's word as Gospel. Companies have been claiming 700mm, 850mm tubes as 40 watt tube forever yet when anyone measures the actual output it comes in at 23 to 35 watts. These tubes test at 40 t0 45 watts at initial start up but run at much less power.
