I'm outfitting my shop with 4 foot, 2 bulb fluorescent lights. I've get about twenty of them. What caring of bulbs should I get? I can't stand the bluish hue given sour from fluorescent. Its hard on my eyes. There are so lots choices and I can't decide. I have need of something as close to sunlight as possible.
The bulbs I have within them already say 90cri, 4000 lumens which be supposed to be close to sunlight I thought.
Do I need what they phone up 'full spectrum', or some specialty bulb?
Thanks in finance.
Answers: If the bulbs you purchased are 90CRI and 4000 Lumens, they are likely T12 (1 1/12 inch diameter tubes) HO (high output) lamp and are considered "full spectrum". While you want a high CRI, these bulbs are typically poor point lamps. This will be as close to sunlight as you will carry with T12HO buoyant fixtures. If you want better quality reading light, you will have to upgrade to any T8 or T5 4ft linear fluorescent. I recommend T8 as they are less expensive and near are high standard light bulbs available.
If you want illustrious quality lamp (bulbs are listed as lamp by manufactures), consider high reading T8 (sometimes called super T8). Sylvania, GE, Phillips, and other assorted manufacture all produce high-ranking performance lamp. Depending on what you actually are lighting, I recommend a 4100K (color temperature) and 85 or greater CRI. The blueish hue are given off by lamp with color temperature 5000K or higher. Unless you are growing plants or own a seasonal light issue, the 4100K lamp with a illustrious CRI will be more than sufficient. Even the high cease body shops use these lamps for paint booths.
I hold listed links below to serve you decide which lamp to purchase. The first two links explain what the different fluorescent ratings mean and what elevated performance lamp are. The third link is to a detail of case studies of a variety of facilities including a couple of professional repair and body shops.
The later link is to a book of high concert T8 lamps and ballasts.
Final Note - DO NOT BUY YOUR LAMPS AND BALLAST AT LARGE BOX STORES! If you want competence and knowledge, try your local electrical distributor. Depending on the distributor, most of them enjoy a lighting expert that can help you.
