If that's true, it's news to me. The last time I checked, fluorescent lighting had the efficiency edge over LED.
Every box or package I have looked at says otherwise. The difference is small, from here on out it will be incremental and not the huge jump seen going from incandescent.
I notice that you used the lumen SI unit. That's what I use for long throw lighting like flashlights and searchlights. But the lux unit is typically used for indoor lighting.
I ran into this when doing landscape lighting, the entire industry is trying to settle on one standard and the preference of choice is lumen. This works better than lux for an all-around gauge because you can still get an idea of light output no matter what the end use is. Lux is well suited for a lighting designer who needs to figure out the correct lighting for a specific environment and task but totally useless for any long range lighting so it doesn't work effectively as lumens for all-around measurement.
Also note that non-CFL fluorescent lighting is common in household lighting. I suspect that a purpose-built fixture will be more efficient than a product made to fit Edison bulb fixtures.
The Edison socket is merely the means of power delivery and doesn't dictate the technology used with it anymore. Regular fluorescent fixtures aren't as efficient as LED or CFL, yes there are high-end fixtures that are but they are very expensive and only seen in large commercial installations.
If LED technology has overtaken pure fluorescent, then I stand corrected.
The light quality from LED is definitely superior! Even the best fluorescent tubes are still obnoxious, the light quality just doesn't quite reach an acceptable level. I know some people are more perceptive of this than others and I am one of those, I can't stand fluorescent light and the cheaper tubes even give me a headache.
But how exactly does that make CFL better for outdoors use?
Sorry, I was not suggesting CFL was better for outdoor use, in fact it was a still-born idea as far as landscape lighting is concerned, the aforementioned cold issues being only a small part of what killed it.
That sure beats the cost of an industrial DMX lighting control system! OTOH my home decor is "real, live rock concert", so I'm still leaning towards the big DMX fixtures.
