really makes (somewhat) lighter

In the table lamp four normal Halos were built. That was too dark. Since the transformer but did not allow a higher power, I came across these bulbs.
At first we wanted to exchange for comparison only two lamps to have a direct comparison between old and new. But there is no difference detected (a physicist can explain why determined).
A difference only after the exchange of all lamps much was evident for us. Although he is not great, but the light has really bright. The lumens specification suggested a brighter light - but still.
We hope that the brighter light is not only imagination and can recommend these bulbs (the price is also not so high).
