Methinks one does not need to be in this trade long to realize the functionality is not apples/apples.

And that this is overshadowed by bean counters .....

The same thing could be said for wind turbines. Not a cheap source of energy but it's "green". LED's are continuously improving compared to what they used to be and the price is coming down. I don't see that happening much with fluorescent technology. I've used a lot of LED's in residential and love the results. It does make a difference on the color you use. Don't rely on pictures and specs etc. It's best to try it for yourself and see what works the best.

Let's suppose that it maintains nominal +/- 5% range voltage, but it jumps around abruptly. If the specifications didn't require flicker or change in voltage over time, it would be "within specs" even though it's realistically unacceptable.


Most LEDs are *fluorescent technology* and phosphor decay is a major part of their degradation.

If you're talking about traditional gas discharge fluorescent lamps, I can confidently say that they have made major improvements in the past few years, such as 90,000 hr (12 hr per start) rated 32W T8 with lumen maintenance performance generally surpassing most LEDs.

You're referring to "for household use only" grade blender like LED apparatus rated on the L70 scale with degradation allowance that far exceeds 32W T8.

What we're talking about here is how lighting that should only be suitable for a gas station was applied in an office lighting.
I installed LED trims in a home office and it worked great! Probably helps it you use the correct light for the job. Same thing goes for fluorescents. It's important to install the correct CRI bulbs for the application. Can I get written guarantee that those bulbs will last 90,000 hours??? Show me a CFL that will last as long as the package tells you. Show me a HO that will keep track of the operating hours of a CFL lamp and return it for replacement.
