7xXP-G in R4 bin, Neutral, on an MCPCB that's 35mm in diameter. It puts out the same light as far as the camera's concerned at 350mA that my 50W halogen puts out at full power. 1/25@f8@ISO100. Around 900lm or so.
There's three times the light to come out of this, easily, possibly more, as they're rated to 1.5A and can take more IF the heatsinking's up to it. I'm going to put these in some MR-16 PAR cans and heatsink them with some holes round the heatsink and a 60-90mm fan pulling air out.
Let's see how the maths go....

It's the temporary one put in a few months back, the one she fought with.... and the tooth is half-dead, unfortunately, so I need to get the root canal work done. I've been putting it off but it looks very much I prevaricated a little too much. Meh!
before you ask: the back at the top. The gap between it and my wisdom tooth was too big and the nice bacteria ate away at the base of the gap, meaning they got the tooth in front rather than the wisdom.

Or pick out your phone for the maps installed.
Sick little one means "working" from home tomorrow, that will be interesting. Need a new firewall after the last one appears to have died a quiet death from some fruit juice... so I have no WLAN at the moment. Most of the time that isn't really a problem, but it would be nice to have again. Ahwell.
'nother R40 to upgrade to Win7, too; just got to do the backup and it should all be over in a couple of hours. Actually, now I think about it, I have an external disk drive box... the smart way would be to reinstall the OS and then copy the profiles directly over from the old install. Have to see if I can pick a hole in that thought.

Lots of reasons:
- Marketing wanted a date set
- we've tested like crazy but there's some strange but common combination we screw up with
- new improvements should be implemented
- mild changes to avoid incompatibilities which are rare but significant
... and that's without mentioning security bugs which are the number one reason you should update EVERYTHING on your computer on a *very* regular basis. It's no longer Windows, it's everything else that runs on the computer that's now the aim of the hackers.
The other point was this: the firmware was probably produced relatively early in the cycle. Only now has someone thoroughly tested the situations which were "real", i.e. there's been code improved with regard to the high ISO buffer limits. The limit was probably there with "justification" in a certain context, but in a photography context for the user the technically correct decision may make no sense.
As such, firmware updates should be greeted - not necessarily with enthusiasm, but certainly as a sign that the company gives a toss and is trying to ensure a good product is in the hands of their customers.
