I bought a 30W LED one for our garden to replace the knackered 500W halogen one that was up there.
Colour temperature is atrocious technically its “daylight”, but it’s more like purple. Fine for washing bikes in, but you wouldn’t want to try and have a BBQ by it.
It’s certainly bright, however the beam angle is stupidly wide (150° mebbe?). Mine is about 15′ up the wall (good reason for this), but the end result is that only maybe 25% of the light is hitting my property. The rest is going into the neighbours gardens, the house opposite, and even the street beyond them!
If you can mount one fairly low, and don’t mine the nasty light colour, then they do what they say on the tin,
