Syska 0.5 W Standard B22 LED Bulb  (White, Pack of 12)

Have been using it for more than a year now in common area which will be on for around 12 hours continuously and it’s fantastic which lasts long

nice and good dilvary TQ

Although the size is big, but its better option then 27 watt stellar bright bulb by Philips if you're priority is brightness and lumens of light output.
I hope company does not stop manufacture these models, because regardless of size some people really need the more bright light. It doesn't look that bad either, especially if you put them on ceiling.
These rocket bulbs aren't availble in market any way, I hope they don't phase them out.
