Makes sense. I'll see if anyone wants any more measurements - if I've got it I'm happy to measure it - the measuring just takes a few seconds to do.
Once that's done I'll tidy up the first post, add comments and qualifications and put in the best data I can get. I've had to work every day for the last month or so, but a colleague has kindly offered to cover this weekend for me so if it works out, I get my first weekend off since June. Then I'll do the tidying. If not it'll get done shortly.
Very nice Don! This is an excellent resource. It's on the frontpage and sticky'd.
Quick suggestion: If you select all the cells in the table and click on cell properties you can set the border color to #000000. It would look like this:
I'll certainly clean it up - at the moment it is just copied and pasted from a spreadsheet - I hope I can make a much better looking table once I've got all the data together.
The biggie for me is the errors - I got bitten hard by that once in a lab job. If my results had been correct, someone was going to jail - it turned out my results depended only on how long the spectrophotometer had been switched on... :(
I plan to go through the light collection and get numbers for most of them. Since I'm doing instantaneous peak readings they only take a few seconds each - it takes longer to make sure I'm using fully charged cells in everything than it does to take the measurements.
Don't you think it would be more useful to take the reading after at least 30 seconds or so - not going for the highest output, but real-life performance?
Great work, Don! You are a real sport to take everyone's input and re-do the tests. It is kind of neat to see how some of them sag after a couple of minutes. I agree some of the lumens readings seem high, but it's still a great comparison of one light vs. another and, man, you have a lot of lights!
If I were to do all of them, it'd take quite a long time. What would be fun would be a way of collating all the information in one place - probably need a lot of hyperlinking to make it useful or the result would be a monstrous mess. I think I have around 100 lights now - will try to get them all in one place and count them some time soon.
