Are you sure you're not looking at SPDs for CFLs instead?

LED lightbulbs at least typically seem to have relatively broad and even spectral coverage, even if the distribution is a little lumpy and only a rough approximation of a BB.

All the SPDs of CFLs I've seen on other other hand, are vastly worse, with lots of super intense and narrow spikes in the middle of large areas of almost nothing.

In other words, CFL SPDs look nothing like a BB SPD, whereas LEDs can kinda-sorta-come-close-if-you-squint (it depends on the particular bulb, but some are not bad at all).

[LED lighting also seems much more likely to improve significantly in the future, as it's been developed for a much shorter time than florescent lighting.]
