Tropicals & Tender Perennials: Can anyone ID this bromeliad?, 1 by cr0ak

I recently purchased this plant from the Mercer Arboretum March Mart. Unfortunately, the woman who was "manning" the bromeliads/orchids section only put the price on it - there was no identifying plant marker, and at the time I didn't think to ask her what, exactly, it was (I was too taken with the gorgeous flower!).

The flower, in this photo, has started to fade, so it's not at peak beauty. But, hopefully, it still looks good enough for someone to be able to ID it for me. I thought it might be Billbergia elegans but the leaves are different.

Thanks so much!
