In my opinion, you really should always be lifting heavy. Everything. Use a weight that's a struggle to bust out 6 reps and break through that. If 75 lb DB's are rough and you feel you can only do 8, work for 2-3 more. Work right before failure. Anymore reps than 12 or 13 will improve endurance only aside from myo/sacro hypertrophy.
In short your workload should be in the 6-12 range if your goal is hypertrophy.
