Review on πŸ’‘ Grensk Filament Equivalent Incandescent Decorative: The Ultimate Lighting Solution by David Edwards

Revainrating 5 out of 5

Really nice very warm little LED lightbulb!

I tried 6 different very warm LED bulbs in different shapes from Revain. I rated at least two bulbs of each type. All species are decent, although some stand out differently. I'm looking for a small LED filament bulb that gives a slightly pink hue (i.e. the yellow-green range) compared to an incandescent bulb dimmed to the same color temperature. Unfortunately, none of the ones I've tried so far fit as I had hoped , to my quest, although some lack the distinctive yellow. The shade. (Note that I am talking about EXCESSIVE yellow tint; all bulbs in this color temperature range tend to look yellowish, but this discussion is beyond the scope of this review.) This Grensk S11 bulb has two small straight LED filaments in a tinted S11 . Glass bulb (small ball bulb with standard E26 socket). My specimens draw about 0.85 watts each, which is a bit under their 1 watt rating! They stay pretty cool even on longer exposures. They are actually slightly warmer than 2200K and approaching 1900K. That makes them even more comfortable I think. They are very similar to the Planckian locust (mountain cricket or lineage) in that they do not have any significant unnatural yellow-green or pink tint that I can discern. Instruments to accurately measure CRI numerically, but they are higher than the typical CRI. They have noticeably deeper reds than typical similar CCT lamps, which are in the low CRI range of 80, and the deep red to white ratio is usually fairly accurate in predicting the overall CRI of a white phosphor-converted LED lamp in my experience . So my verdict is they probably have >90 CRI as advertised. I haven't tried to discern the light output, but I have no problem believing it's close to the claimed 80. I can't even talk to the lifespan values. , as I have never burned any of the lamps of this type for more than a few hours. I'm not sure what the "thickness" rating would mean, so I didn't rate it.

Pros
  • β₯ Cool Retro LED Bulb: Small Edison bulbs with elegant amber/gold tint glass cover, when you turn on the lights at night, the bulbs will show off your lights beautifully. The ultra warm color is especially suitable for night walks, night time. Gatherings or festive ceremonies can also create a romantic and relaxing atmosphere, and it is a good choice to replace 25ft Edison LED string lights and all festive occasions.
Cons
  • Out of fashion
