Daylight savings is just around the corner, so of course we'll all be doing a lot of 'light calls' as usual.
I get a lot of Q's about efficent lights, what's good, what's not, what to look for, etc.
The hardware stores and depots are full of choices, but not all are marked with the same info.
Myself i look for wattage vs. lumnems, but it may not always be on the package.

Any suggestions out there??

Lumens don't tell you the color.

I hate to be the one to break this to you, but DST is here. Soon we'll be going back to standard time. It doesn't really make sense that we are on standard time less than on daylight savings time... but that's the way it is. (Offer void in Indiana, Illinois, Arizona, etc.)

Try this:

The Sylvannia catalog can provide much info on all types of lamps.
And if more info is needed on color, try the IES Handbook. Color is rated in degrees Kelvin, and 4100K is a yellow color (if my memory serves me correctly), 3500K is more to the natural sunlight. We typically use 4100K bulbs in some pharmaceutical manufacturing process areas.
