LED vs Fluorescent
Against:
- Even the highest efficacy LEDs have not reached the efficacies of the highest efficacy fluorescent lights.
- The lowest cost lower efficacy LEDs have not reached the efficacies of low cost linear fl or CFL.
- LEDs' upfront cost is much higher for anything beyond extremely small light outputs.
- LED light quality is poor compared to fluorescent.
- LEDs are not available in powers comparable to fl lights
For:
- Some, but far from all, LEDs have much longer lives than fl tubes. Many have shorter lives
- LEDs are more mechanically robust
- LEDs in very low powers are much smaller than fls
- The lowest power LEDs (fractional watt) are available in sizes 2mm to 10mm.
Things may change, as LED performance is getting better year by year. But they have not got there yet, despite the hype.
