The new lighting system on the Evolution eliminates shadows! Fabric and thread colors appear clear, true, and distinct. When I was looking for a new serger, I demoed 6 different brands. All their sewing areas were lit by a bulb which turned the fabric different colors and caused the foot to cast shadows on the sewing area. Finally, I found the new BabyLock Evolution! The sewing area is illuminated using a LED lighting system. The light literally surrounds the needle area. Since it is a different type of light, the fabric colors remain true. Most importantly, the foot doesn't cast a shadow on the sewing area! My eyes aren't what they were 20 years ago. The new BabyLock Evolution allows me to see clearly and to serge accurately, no more WOOPS!
