Can we hack an Energizer lamp for longer life?

Well of course we can. Here's how to do it.

Note the "15 year life" is based on 2.7 hours a day, so actually 15,000 hour life, or more likely until you lose the receipt. But with this hack 15 actual years is possible, as it reduces the LED power dissipation and therefore heat significantly. Intensity will be slightly lower, but still very acceptable.

Very typical design, suggesting a "name brand" being applied to a generic lamp. But sensible and familiar circuitry that is easy to tweak.
