lighting help

i have a small desk lamp with a 40 watt bulb with 1180 lumens and a 15 watt flourescent tube with 900 lumens inside my box. is this gonna be alright cuz im going back to buy another florescent tube today do 900+1180+900=2980 lumens total. is this gonna be fine or is it too fire risky. if so what can i buy to add with my 900 lumen flourescent tube to get a good amount of lumens.
