What's the typical LED bulb efficiency (l/w) in your country? « on: July 10, 2025, 02:17:51 PM » Author: macusking
Here in Brazil the regular led bulbs are pretty garbage both in operating life and power efficiency.
the norm is something like 89 l/w, some bulbs get as low as 80 l/w. Both 3000k and 6400k variants.
At the same time, we had some CFLs with 64 l/w, almost as high as the LEDs.

In your country, how efficient are they?  :eoled:

Essentially 3 flavors:
- Bog standard 100lm/w CRI 80 - also usually what's in fixtures with non user replaceable electronics.
- Ultra efficient home use 210lm/w cri a claimed 80, but with a very clear color tint shift (not at the black body radiator white point, pretty bad)
- Ultra high color quality 90lm/w, CRI 94.

The standard and the ultra efficient ones are the easiest to just buy in stores, but if you order online you can also easily get the others.

Under European directives our LED are an average of 117 lm/W, i.e, a 13 watt filament LED is 1521 lumens 😎
CFL here are the same as Brazil @ 60+ lm/W

In the last year or so, the minimum is around 100lm/W, usually at 90+CRI 2700K for the name brands, 80CRI for the cheap ones (for an incandescent retrofits, dedicated LED lanterns usually do not bear lumen rating), maximum efficacy uses to be in the 130..140lm/W at 80CRI 2700K
