I received my two pairs of CCFT lamps fro
All Electronics yesterday.
I hooked one pair up to a 12 volt battery this morning and measured the voltage and current.
12.8 VDC
0.73 amps
That means they consume 9.344 watts. If my memory is correct, the incandescent lamps in the fixtures Casita uses draw 1.5 amps. One pair of these CCFTs use half the current and the light appears to be at least twice as bright (I have no way of measuring the light output).
I'll try the CCFTs in the Casita when it cools down some here (it got up to 100.6º yesterday). I'll try them first just mounted to the fibeglass bottom of the overhead cabinet and see if they provide lighting comfortable for reading. I wish I had old 12" flourescent fixtures like Mike used, the diffuser would help and the installation would look better.
Thanks to all of you for the information I used to buy these. They look like winners for an old boondocker who likes to get up early to read and work crosswords.

Just an update; the above post was last June and it applied to the Dual 12" CCFT kit by Logisys.
I recently purchased 2 Dual 4" CCFT kits by Logisys. They're packaged in the same box as the 12". The specifications on the box are for the 12". I measured the 12VDC current for draw the 4" pair using the same setup.
12.8 VDC
0.33 amps
That translates to 4.224 watts consumed by the 4" pair.
Anyone considering the 4" CCFTs should understand that the specifications on the box which is copied by the vendors are incorrect. The brightness (I'm assuming they really mean luminance) is specified as 28,000 to 30,000 cd/m**2. Don't expect that output from the 4" tubes. I'd guess about 1/3 of that luminance.
