Would you be so kind to post a reference link to your statement ?
I remember not too long ago there was a discussion on here and some good references just to the contrary. That MH bulbs only loose 20-25% in 12 months.

If the corals are still just as colorful, growing and no algae problems then I don't see the need to change a bulb at a fixed interval just because somebody says I have to. Every bulbs life is going to be different based on mfg, hour usage, temperature control, brand of fixture they're in, etc. This were I don't agree with LED mfg's using short bulb life of non-led's to help justify their high prices in their marketing schemes showing how much money you will save every year on bulb changes.

+1. many of the high end units require a board replacement if an led burns out. Haven't heard the cost to replace one board but I imagines it's HUNDREDS of dollars.

The big thing too is many of us change tanks every few years or quit the hobby.6 + year payback isn't realistic IMO.
