What is the best type of light to use for comparisons? I know fluorescent isn't the best and incandescent is better, but is there a particular type of bulb that would fit in a standard fluorescent lamp that provides better illumination? I know this becomes an age-old question and was hoping that someone had some suggestions. I have a lamp that I can use for harder comparisons but really need something that will work in overhead fluorescent lamps.

The human eye was designed to work best in natural sunlight. I heard of one lab that bought lights from a medical supply outfit that were designed for dentists to use for their exams/cleaning/fillings, because the light was supposed to be as close to sunlight color balance as possible. Probably not a bad idea, either, to ask an opthamologist next time you go for a visit.

Have you tried a lamp from this company?

I really like my Ott-Lite for comparisons when I need something really well lit. For the most part I just rely on indirect sunlight. However, I'm also lucky enough to sit in front of a window that faces north so that I get constant diffuse natural daylight and 300+ days of clear skies each year.

Based on SConner's suggestion, I contacted Ott-Lite and they don't sell bulbs for standard fluorescent fixtures--they did suggest Phillips as they have a "daylight" bulb that is close to 5500K (which is what I'm looking for, right?)

That brings me to my next question, then--possibly for ER. What lamp are you using from Ott-Lite? Do they all have the same bulb--maybe that's what makes them unique--it doesn't matter what lamp you have since they all use the same bulb. From what I've gathered, that is the case but for those that have one, can you verify? Thanks.

When I worked for Newport Beach PD, I put all daylight fluorescent bulbs into the photo lab because we did some photography there and I wanted to avoid a color cast. They work great for that, and I definitely recommend them if that is your goal. But, don't think that they are easier on your eyes or will provide better light for comparisons - they don't. They suffer from the same issues that all fluorescents do - they aren't any brighter, when they get old, they flicker, and they simply aren't easy on your eyes. I recommend using a separate light, on your desk, for comparisons (well, actually, I recommend scanning or photographing prints and doing comparisons on a nice, large computer screen). You want a "task light" that has a bright bulb and an adjustable arm so that you can control the direction and intensity of the light. I would suggest also having some sort of diffusion lens in front of the bulb so that the light is softened.

Josher, on their website they have a full range of desk/table/task lights that they sell, that's what I was assuming that you'd be most interested in.

They're not inexpensive but that's where the unreimbursed work expense on your taxes write off is useful

My Sweetie insists on Ott Lights in her sewing room. She swears by them, but oddly enough, I have never thought to try comparing fingerprints under one. Maybe I'll "borrow" one of hers and take it to the office for a few days.

Ott-Lite had (or has) a sale on the majority of their desk lamps so I broke down and bought one. It arrives today and I'll be posting my initial thoughts here in case anyone that doesn't have one is interested. I got the Black Executive Desk Lamp because the neck has the ability to move around a bit. If you read some reviews on their site, they don't always get high marks but on amazon.com, they are getting glowing reviews. Still, for $42 (after shipping with the 20% discount they offered on top of the sale price) isn't a ton--AND--I'll deduct it this year. Hope they are all they are cracked up to be. If not, I'm coming after you, ER and SConnor (just kidding).

George, I do most of my comparisons on computer but for quick side-by-sides or latent to known inked (victim elimination) card, I still use a magnifier.

As promised, the light arrived and I even let it come to room temp before turning it on (it's about 15 degrees outside now).

The lamp was mostly put together; the bulb inserted easily and it puts out a decent amount of light. It's a great color and is right between the warm and cool settings of tungsten and fluorescent. I really like it so far and am glad you all suggested it. Now, back to comparisons!

I'm not in any way affiliated with Ott-Lite but for those that are interested, you can type in PLUGGEDIN at checkout and get 20% any item (including those on sale).

As requested, my Ott-Lite bulb is an "OTT-LITE Vision Saver - 13W"

I have been using an Ott-Lite for several years and love it.

For those of you living in a decent sized city: your Sunday newspaper likely has 40% off coupons to the chain hobby/sewing store and most of those stores (our local ones are Hobby Lobby, Michael's and Jo-Ann if that helps) carry a large selection of Ott-lights. They usually have 50% off or more sales once or twice a year or you can usually use the coupon for a new lamp and/or replacement bulbs.

I've also found them on Craigslist under the "Arts and Crafts" section. They are very durable and the light is amazing and doesn't hurt your eyes.
