Worked example

The scenario below is illustrative. It is not a description of the reviewer’s business; it shows how an electrical business like the one in the review would use Lux Meter Pro.

The situation

Consider a ten-person electrical business doing kitchens, LED spotlight installations and home improvements. The conversation that comes up on almost every job is some version of: will six spotlights be enough, or is this new fitting really brighter than the old one?

Homeowners judge light by feel, and feel is hard to argue with. When the customer is not convinced, the electrician either adds fittings they did not quote for or spends the evening explaining lumens over the phone.

How Lux Meter Pro fits

Before the work, the electrician takes a reading at worktop height under the existing fittings and keeps the card. After the install, the same spot gets another reading. The customer sees two numbers rather than a shrug, and the difference is the thing they paid for.

For a kitchen or a larger room, a lighting grid shows where the light is even and where it falls off, which settles the question of whether a seventh spotlight over the sink is worth having. The grid PDF goes into the customer's job file.

The reviewer runs Lux Meter Pro alongside a job-tracking app, which is a sensible pairing: the readings and PDFs live with the job, so when a customer asks a year later what was installed and how bright it was, the answer is on file.

What it changes for the business

  • Fewer not-bright-enough callbacks, because the output was shown and agreed on the day.
  • Extras such as an additional fitting are justified with a reading rather than a hunch.
  • A professional record for the customer that most competitors do not provide.

Key takeaway

For installers who sell lighting as an improvement, a number the customer can see is worth more than any description of it.
