OK two very similar bulbs, both 5W both LED, Both globe, both 180° both marketed by Ecolight one part number EC79130 the other EC79129 being 6500K +/- 500K and 3000K +/- 200K and 440 lumen and 420 lumen being classed as daylight and Warm White.
I will admit I did not even notice the difference until fitted in the same room, I had 10 x 3W candle fitted in one room, and after fitting 3 daylight globe lamps in the other room, it seemed a good idea to fit globe lamps at 5W to replace the 10 candle 3W bulbs when I had found some where to use the 3W candle bulbs which were being removed.
The gain did not seem to be as much as with other room, but until I fitted three of each in the same room I had not realised one set was day light and the other warm white.
So with the room with 10 lamps, although the 5W were brighter than the 3W, the difference was not that marked. But moved from 2300 lumen to 4200 lumen not quite twice as bright. I should have needed sun glasses.
This is not the first time lumen and brightness perceived does not seem to have lined up. But the two ends of the room with 3 day light and 3 warm white is very marked, OK whiter that is to be expected, but 1320 lumen v 1290 lumen seems very marked, when 2300 lumen v 4200 lumen hard to tell the difference.
What's gone wrong?
