Review (a bit negative): Osram
Review (a bit negative): Osram LEDriving / Sylvania Zevo / Hella white LED bulbs in festoon format. This design is identical in size and shape to filament types, and has an all-around light generated by two chips behind a subtle diffuser lens.

These seem to be intended to replace 5 W filament bulbs although in the 41 mm size tested, 10 W originals are common, and as demonstrated they are nothing like bright enough to substitute for 10 W. The configuration means they best suit light enclosures with a reflector. Available in 4000 K "warm" (more of a neutral pure white) or 6000 K "cool" (i.e. blue). For interior lighting I believe the former is preferable.
Reviewed characteristics include the bulbs' design, power, color, and comparative brightness.
* Claimed: 4000 K "warm" / Measured: 3800 K "neutral"
* Claimed: 1 W / Measured: 0.9 W
* Claimed: 3x brightness / Perceived: about equal to a 5 W filament
* 5 year non-commercial warranty.
