Lighting & home climate · Est. 2019

Light that knows when you need it.

DWEPTU builds the small lights that make a home feel finished — under-cabinet bars that flatter a countertop, night lights that sense a footstep, desk lamps that fold into a drawer, and climate displays you can actually read. Warm, quiet, and engineered to be forgotten.

How we build

Four decisions we refuse to compromise on.

Every claim on this page is measurable, and most of it is measured in our own lab in Zhongshan.

01

Light measured, not guessed

Every production batch runs through an integrating sphere for lumen output, CRI and color temperature. The numbers on our labels come from that test, not from a datasheet.

02

Warm by default

Our house color temperature is 2700K. It reads as evening candlelight on skin, stone and food — the reason our return rate for “too blue” sits under 0.4%.

03

Install without a drill

Adhesive, magnetic or plug-in mounting on every consumer fixture. Renters are half our customers, and they should not need a landlord to install a light.

04

Fifteen-year parts promise

We keep driver boards, diffusers and mounting clips in stock for fifteen years after a product launches. A dead light should be a $6 fix, not a landfill trip.

DWEPTU photometry lab

Since 2019

We started by fixing one diffuser.

Two engineers in Zhongshan bought every under-cabinet light on Amazon, took them apart, and found the same flaw in all of them: a clear lens over bare LEDs. The first DWEPTU bar replaced it with a co-extruded diffuser. Four thousand people bought one in the first quarter.

Seven years later we still begin with the part you look at. The lab came later — an integrating sphere, aging racks, thermal chambers — because a claim you cannot measure is just a nicer sentence.

Where to buy

Same product, same warranty, three storefronts.

Buying through a marketplace keeps their returns process. Buying direct from us is on the roadmap for 2027.

Ask the people who designed it.

Our support team and the fixture engineers read the board every day. Color temperature arguments, sensor placement, humidity offsets — this is where those get settled in public.
