Where can I get Energy saving bulbs more powerful than 25w for a brighter
light ,something equivalent to 150w Thank you E

Haven't checked for a while, but Homebase did a 30W one, only
available with an Edison Screw lamp base though.

The trouble with higher power ones are that the heat from the
tube cooks the electronic control gear if run base-up. Higher
power ones are more readily in the US, but they usually come
with a warning that they must not be operated base-up or they
will suffer shortened life. You can find them mail-order in
the UK too.
