Brightness
Brightness is how much light a lamp gives, and it must fit the task: lash work needs bright, close light on fine detail, while salon work needs moderate, even light over a client. A lamp that is too dim will leave the professional guessing, and a lamp that is too bright will glare and tire the eyes. Brightness should be judged in the workspace it will serve, not in a showroom, because workspaces reflect and absorb differently.
Brightness should also be adjustable where the task varies: a lamp that serves both close detail work and general salon work needs to dim for one and brighten for the other. A fixed-brightness lamp that serves one task well may serve another poorly, and adjustability is what lets one lamp serve several tasks. The beauty lamp selection guide explains the types by task.
Colour truth
Colour truth is whether the lamp shows colours as they really are, without tinting them. Makeup lighting needs colour truth above all: a lamp that tints colour will mislead the artist, so makeup that looks right under the lamp looks wrong in daylight. Lash and nail work need colour truth too, though less critically: a lamp that tints will hide detail and distort the work's appearance.
Colour truth depends on the lamp and on the room: a lamp that is true in a white room may tint in a coloured room, because walls bounce their colour into the light. A neutral workspace, and a lamp confirmed for colour truth, will show work truly. The inquiry should name the task and the workspace, so the supplier can confirm a type whose colour serves them.
Adjustability
Adjustability is whether the lamp can be positioned, aimed, dimmed, and, where it has it, magnified, for the task at hand. A lamp that cannot be positioned for the hands, the face, or the eye area it serves will fight the professional instead of serving them. A lamp that cannot dim will glare on close work, and a lamp that cannot magnify will leave fine work unseen.
Adjustability should be judged by the tasks the lamp must serve: one task may need one position, while several tasks need several. A lamp that serves several tasks needs the adjustability to move between them, and a lamp that serves one task needs only the adjustability that task demands. The inquiry should name the tasks, so the supplier can confirm the adjustability they need.
