R50 compact fluorescent

[Andrew Gabriel]

Just seen R50 7W (claims 40W equiv) compact fluorescent retrofits
in IKEA. Bought one and tried it and it seems remarkably effective.
The lamp is a flood lamp rather than a spot lamp, but there's no
light spill backwards. Amusingly, the whole case is clear plastic
so the electronics are visible at the rear, although this area is
slightly frosted. They also had some candle lamps and golfball
lamps which are smaller than I've previously seen any retrofit
compact fluorescents.

40/7 is 5.71. Typical ratios between CFL and incandescent are 4:1. I
don't see the lamp on the IKEA site. Can you provide a reference?

Whoops -- just checked again and it's a 25W equivalent, sorry.

IKEA part number is 400.606.24, although that's a 220-240V lamp
of course in the Uk. My attempt to search their website produces
a only a list of javascript errors.

i worry about the ballast in this environment. the fixture is vented, sure, but
designed for much higher temps and many spot fixtures would qualify as an enclosed
fixture wrt to electronic ballasts.

Phillps has a new, "directional" incandescent bulb, intended to replace small
spot/flood bulbs. i replaced a 75w standard (not R60) with a 60watt Phillips
into a really aging spot fixture and it was indeed much brighter. don't have
the figures but it was 2-3x. of course it was old vs new bulb, too. --Loren
