Describe the task
Record where the light will be used, what the user needs to see and whether one or both hands must remain available. Separate handheld and headlamp requirements before comparing products.
Set practical limits
Write down acceptable size and weight, preferred battery arrangement, charging access and controls. Identify which requirements are essential and which can be negotiated.
Compare complete specifications
Request output by mode, runtime conditions, beam information, protection documentation and supplied accessories. Leave missing information as unconfirmed; do not assume that similarly named products share specifications.
Evaluate a sample
Check grip, mode sequence, charging access and packaging against your brief. Confirm the configuration and final specification in writing before placing an order.
