ZPG Light Lab

Runtime details separate manufacturer ratings from third-party tests. ANSI FL1 runtime ends when output falls to 10% of the 30-second reading; it does not mean full brightness for that whole duration. Charge times are from empty and vary with power supply and temperature; measured times are labeled. Select the lights you want to compare. The same chart serves Help me choose and Browse lights. Selected lights stay in the chart when you switch views or change filters; remove any row to narrow the chart. Show all specifications to see output levels, runtime, battery details, controls, and finishes. On phones, each feature lists the selected lights and their values. On larger screens, use the table. Differences only hides matching specifications in the current view; a known value versus an unconfirmed value remains visible. Tradeoff highlights compare only the selected lights with complete, confirmed numeric fields. They are not overall scores. Weight values can use different measurement conditions; check the stated basis. Output levels show steady white-light modes, with lumens and rated distance side by side. Maximum output is temporary; automatic step-downs are not extra modes. Open additional beam groups for their levels. Stepless shows the low and high limits. — means a value is not confirmed; distances are never estimated from lumens. Coming-soon specifications may change. USB-C may require the case, base, or holster named in the charging column. ZPG availability and quantities are checked live when you search. Quantities total available listed variants; sold-out and backordered variants are excluded.
