Light is very punctual

The LED bulb to replace a 25W candle bulb in a globe. According to the information available the lumen number is higher than the 25 W bulb. But it is so that the candle bulb lit up the world equally. The very short and small LED bulb produces a very punctiform brightness in the lower half of the globe, which it appears quite dark in the upper half. So, overall, the subjective impression that the number of lumens 25W bulb would be higher than that of the LED bulb.

Execution: The LED's are "poured" in silicone. That looks very unusual and if the light transmittance is maintained in the long run, was once an open question (like all the promises at all LED lights). Otherwise I can say little to, and I hope that even so remains, which means that the lamp itself behaves years satisfactory.
