Today I headed out into to cruel, understocked world, to pick up a few items to begin my lighting experiments. Prices were noticeably better at the BORGs than online. Along with a few fixtures I came home with the bulbs:
Sylvania ("Spectre Maximal"), T8, 32w, 5000K, 1800 Lumens, CRI-90.
When I got home I noticed that Phillips has a bulb: T8, 32w, 5000K, 2850 Lumens, CRI-85. I believe Home Depot had those in boxes of 25 (only), which is why I passed them up while I was there.
I came home with a few of the first sort from Menards. It's the difference in "Lumens output" which has me concerned:
In Sylvania's catalog, their bulbs above (1800 Lumens output) were suggested for "display, signage and backlighting". This is leading me to believe that they may be inappropriate. ***Agree???*** Please advise me whether I should return what I have and get a box of the Phillips bulbs. Any other comments which will further my education about this are of course welcome too!
BTW, In Sylvania's cataglog, it says that 850 Lumens ~ 60 Watt incandescent bulb. I'm not sure if multiples of this relation are meaningful (probably not). BTW2, I did notice that the Lumens Output listed is a "nominal measurement" (ha) --one may be doing well to actually get 80% of it.
I finally got a big binder last night to hold my plans and designs in. That's got to be better than the approach I was using. ;)
For those of you who remember my broken dishwasher: It washed and washed at 100 decibels or more for the past few months (I was adhering to the suggested "if it's not *really* broke, then don't fix it" principle). About a week ago it tripped the GFCI switch it was on leaving my poor wife to bail the dishwasher out by hand. I noticed a 10% sale at Lowes last week, and got an additional 5% for getting a Lowes CC, so I bit the bullet. I pondered how many light fixtures and wire you can get for the price of a new dishwasher, but as my wife seem to take pride in pointing out..they don't wash dishes! ; )
Sorry if I've distracted you, my main concern is about those 2 categories of 5000K, T8 bulbs.
Thank you, Bill
