I have these LEDs are open in the vorme 3x ceiling spotlights in bathroom with cylindrical glass bulb. One can look directly into the LED lamps. There matched previously only E27 round bulbs that were permanently broken and the exchange was extremely difficult. The LEDs fit in exactly, the viewing angle is great for this lamp.
The light color is really warm white and similar to a light bulb. Brightness is subjektv significantly brighter than 25W, rather almost 40W.
I have several LEDs of the manufacturer in use, with the same positive experience.
