Blue LED C7 Replacement Bulb Review

I bought several of these to use as decorative accent bulbs. They are great for that purpose. They run cool, burn little energy and burn almost forever. The white bulbs are bluish. The colored bulbs are spectacular. The colors are incredibly vibrant. Like laser light.
I don't know what country manufactures these. They are not marked. I've had several of these running constantly for months now. There have been no failures. Despite what another reviewer said, the quality seems fine.

Feit Electric BPC7/LED Three LED Night Light Bulb with Candelabra Base, Clear, 2 Pack Review

First, let me warn everyone--if you need a bright night light, do not buy this LED replacement. However, for many people, the Feit Electric BPC7 will be satisfactory. I have tried several LED night light replacement bulbs. They vary widely in quality and light output. This LED bulb does well in both areas.
The bulb puts out a moderate blue-white light. I have heard from some long-term users of similar products that it may become more blue over time (we're talking about years here). The color of the light may take getting used to, but it is pleasant and does not disturb sleep when getting that late-night drink of water.
For those of a technical mindset, commercial LED night light bulbs come in a couple different forms: full-cycle, rectified circuits or half-cycle circuits, which have a resistor and/or capacitor. A full-cycle LED is capable of producing near-constant light; a half-cycle LED will produce light pulses as the circuit cycles on and off (approx. 60 times per second, if attached to the U.S. power grid). When thinking about light quality and bulb longevity: a rectified LED cicuit is what you want. It is the type of circuit you will find in the Feit Electric BPC7. Maybe that is why they can offer a lifetime guarantee. None of the other bulbs I tried have this guarantee. (Please note: I am not an engineer--this is based on my own understanding of LED circuitry)
