The short version
A headlamp is essential; a waist light is what makes technical trail readable. Light coming from your forehead travels along your line of sight, so rocks and roots throw almost no shadow and the ground goes flat. A light at waist height comes in low and sideways, casting shadows that show you which lumps are rocks and which are just texture. Most experienced night runners carry both and it is the second one that changes the running.
Common questions
How many lumens do I need?
Fewer than the marketing implies. Two to four hundred lumens with a good beam pattern is plenty for trail, and running a lamp on maximum burns the battery in a fraction of the stated runtime. Beam shape and battery life matter more than the headline number.
Rechargeable or batteries?
Rechargeable is lighter and cheaper to run, and it needs a plan for a long night. Swappable batteries can be replaced in seconds at an aid station. Many races require a spare light source or spare batteries regardless, so read the rule.
Does red light help?
For preserving your own night vision and for not blinding people around you at an aid station, yes. For seeing trail at speed, no. Use white for running and red for camp.

Choose the Black Diamond Spot 400-R Headlamp if…
You need one light and it needs to satisfy a kit check. A headlamp points where you look, works for reading a map, digging in a drop bag or fixing a shoe, and is what every mandatory kit list asks for. Carry spare batteries or a spare lamp: kit lists usually require that too, and a dead lamp at two in the morning ends a race.

Choose the FlipBelt Night Running Waist Lamp if…
You run technical ground at night and the trail keeps surprising you. A waist light throws long shadows that make rocks read as rocks, and it also cuts the glare that a headlamp bounces back at you in fog, rain and dust. It is a second light, not a replacement, and it does nothing useful when you turn your head.
