runs cooler and lasts longer. This was at the urging of the government of t hat country and now these light bulbs are mandated but likely are two or th ree times more expensive than the units we get that have to compete on pric e resulting in less efficient lamps that burn out quicker.

Sounds like you would have been better off not asking then. Why do you car e? Why are the zeners any issue? The point is the gadget gives a signific ant efficiency boost. It has much more redundancy than you would expect in a consumer product, but that seems to be what was required to get a better product to market.
In competitive profit driven markets this device would have never seen the light of day. By the same token, CFLs and LEDs have benefited by many gov ernment promotions and regulations because when you could buy an incandesce nt bulb for $0.25, no one would want to pay $5 for a more efficient bulb. Now it's hard to find an incandescent bulb because the public is educated a nd understand the cost effectiveness of a $5 CFL or $8 LED bulb. But they don't understand the $12 LED bulb with two or three times the number of LED s is more efficient and longer lived. I just wish I didn't have to change out all my ceiling fixtures to use them. Funny how the emphasis used to be on keeping cool the structure supporting the hot light fixtures and now it is keeping the bulb cool and not burning itself up.
