$20 DC floodlights shootout - China reviews
Channel: FFcossag
Date: 31/10/2014

Four models of Chinese LED floodlights in the roughly 20-dollar segment are tested here. Two models stand out at opposite ends of the spectrum of performance. One is a better performer than the others, and one is the most sensible of the lot.

Spoiler: NONE of them live up to their specified power.

Keep in mind that the testing methodology used in this video does not account for light spread, so widely-throwing lights are at a disadvantage, and it shows in how the "18 W" model looks so good despite measuring so poorly.

Note that I refer to the lights by their advertised power, which is NOT the same as their actual power, and especially not the same as the power going to the actual LEDs. Actual power going into the LEDs is probably closer to:

11,5 W for the "18 W" model,
16,5 W for the stronger and 12,5 W for the weaker "24 W" model, respectively, and
17,5 W for the "27" W model.

The 24 W and 27 W models also have four mounting holes on the back in an 87x2,54 mm pattern, ganged with some imperial thread slightly larger than M4. They can also be found for sale at Clas Ohlson, with a cheaper lens assembly, and for roughly four times the price.
