Not sure how to review a light bulb... Does what it supposed too... Light up when voltage is applied and it performs as advertised

As the note for these bulbs says on Aircraft Spruces web page, these bulbs may not have been made by GE and could be manufactured by others which was true in my case.
I purchased 6 of these non-GE bulbs for my Piper Arrow as replacements for the GE-330 bulbs (one of them failed and I figured that I would just replace them all and have a spare set. However all 6 bulbs failed as soon as I turned on the power. Some had filament failures and others had filament failures that broke the glass. So instead, I purchased 3 LED replacements from Aero-Lites (pn: al-330mf-cw) and all is now good. They are quite a bit brighter than incandescent bulbs so you may need to change the resistance on the brightness controls or go with their 28-volt version. Aircraft Spruce refunded my money and I suggested that they only carry the LED alternative. Sure, about 6X more expensive but who wouldnt want to spend the extra money to get reliable three-greens!
