Energy Saving Lightbulbs
Hi,
Can anyone please tell me if there any energy saving lightbulbs on the
market that have an equivalent output to 150W incandescent bulbs? Its
just I find that the manufacturers claims don't hold true when it
comes to equivalent output.
Many thanks!

I doubt it! I'm not sure that any even *claim* to do so and - as you say -
most of the claims are a gross exaggeration. I can only assume that they use
the grottiest incandescent bulbs they can find when making the comparison.

The comparison is made against soft tone lamps, not GLS lamps.

Ignore manufacturer's claims and use a general 1:4 ratio for
plain energy saving lightbulbs. (Reflector ones are a lot lower.)
So using this, you need a 37W lamp. The highest I've seen in
normal retail outlets is a 30W lamp in Homebase, screw fitting
only. Costco have some 25W ones (Feit) which seem quite good in
packs of 4, but are going to be nearer 100W equiv. I've got several
in use and no problems so far, but they're only a few months old.
These higher powered ones don't last as long operating cap up,
because the tube generates lots of heat which roasts the electronics
in the lamp base. You can get higher powered ones from specialist
mail order suppliers.

Re: Energy Saving Lightbulbs
Can you please tell me which specialist suppliers sell higher powered
bulbs. I can't find any using Google.
Thanks.

Megaman make high power CFL (not very C).
If you google for them and see what else the supplier sells.

As an aside, if a 150 watt is currently used in (say) a central light
fitting, would it be better anyway to change the fitting for 2 or 3 others
to spread the light better. 150 watt is a bit intense in one location (in
some cases)

Re: Energy Saving Lightbulbs
Thanks for the reply. The Megaman WL130 would have been great but its
17.6cm long! Its far too big for my needs. I'm guessing a 30W GLS
shaped one does not exist right?

No. The homebase one I mentioned is 17cm long (if they still do it).
In terms of size-for-size replacements, anything over about 10W
(i.e. 40W GLS equivalent) is going to be bigger than the GLS lamp
it replaces. CFL's are slowly getting physically smaller, but that's
where they're at at the moment.
Also, the more compact the folding/coiling of the tube, the less
efficient as more of the tubing becomes obscured by itself resulting
in lost light output.

150W filament lamps tend to be large.
What are you using the lamp for and is it mounted in a fitting which
can stand the heat?

Re: Energy Saving Lightbulbs
I ended up getting these GE 20W GLS:
http://tinyurl.com/5kdcyj
I have two downstairs in the hallway and three upstairs on the
landing. They work great and I can't even really tell the difference
in brightness between the 150W ones they replaced. I tried them in a
bedroom and my study but its not bright enough and also I don't like
the lighting for reading etc in those rooms.
Cheers!
