Realky 20 W floodlight review

A 20 W floodlight with 72 LED emitters at 2,000 lumens and 6500 K, in a die-cast aluminum housing with an adjustable PIR sensor.

The conclusion Aluminum at a plastic price, which is the right trade. IP65 and detection up to 12 m (39 ft) stated.

Cheap floodlights do not usually fail because the LEDs wear out. They fail because the LEDs cook.

Heat is what kills them

An LED emitter has a life measured in tens of thousands of hours at its rated temperature and a small fraction of that when it runs hot. A die-cast aluminum body conducts heat away from the emitters and into the air; a plastic one holds it in.

That is why the housing material predicts the life of a cheap floodlight better than any figure on the box, and why this one is worth its money.

72 emitters

More, smaller LEDs spread the light across the beam rather than producing a hot center with dark edges, and they share the heat between them. It is sound design at this price.

What the listing publishes

An IP65 rating, detection up to 12 m (39 ft) across an adjustable 180°, and three controls: TIME (on for 7 s to 9 min), SENS (range from 6 to 12 m) and LUX (light threshold). The beam is stated at 120° and the LED life at over 20,000 hours. An eave is still good practice: rain on the lens and water at the cable entry are what end floodlights.

The color, again

6500 K. Effective, harsh, and the reason neighbors complain. Warmer lights show an approach just as well.

Who it suits

An exposed position where the light will run hot, under some shelter.

What reassures, and what does not

Strengths

  • Die-cast aluminum housing, which is what sheds heat and keeps LEDs alive
  • 72 emitters spread the light more evenly than a few large ones
  • Adjustable PIR modes
  • Cheap for an aluminum-bodied light

Compromises

  • 6500 K, the same harsh color as the GRIFEMA
  • 2,000 lm from 20 W is slightly less efficient than its rivals here
  • No ambient light: it comes on at detection, then goes off
  • Detection limited to 12 m (39 ft), against 21 m (69 ft) for the Philips

The questions we are asked

Why does the housing material matter?

Because LEDs die of heat, not of use. A die-cast aluminum body conducts heat away from the emitters; a plastic one holds it in, and the light dims and then fails years early. It is the single best predictor of how long a cheap floodlight lasts.

Are 72 small LEDs better than a few big ones?

Usually, for even coverage — many small emitters spread light across the beam rather than producing a bright center and dark edges. They also share the heat, which helps. It is a reasonable design at this price.

What is the IP rating?

IP65, stated by Realky: dust-tight and protected against water jets. An eave is still good practice for any floodlight, because rain on the lens and water at the cable entry are what end them.
