* The 50/50 provides the benefits of Coralife's Daylight 6,000K Trichromatic phosphors with their 7,100K Actinic phosphors blended equally.
* The combination provides the versatility of two lamps in one package.
* 50/50 bulbs are good if you want a more subdued blue hue in your tank. Since there's a mix of phosphors, the bulb is not a bright as a full spectrum daylight.
* Note: Some bulbs are shipped to us without their outer bulb sleeve. If you must have the factory sleeve with the bulb, please note it in the "Comments" section on page 2 of the order check out. This may delay your order if we're out of bulbs which do not have sleeves. Thank you for understanding.

FAQ:
Q. Some of my bulbs seem to be dark at the ends, is this used?
A. Some bulbs have a slightly darker end to them when they arrive from the factory. Sometimes when you test a bulb (we light all bulbs before they are shipped), it will have a slightly dark end. There is nothing wrong with the bulb, and the phosphors inside remain perfectly useable.
Q. I plugged in my new Coralife bulbs, and noticed a slight flicker strobing effect at the ends, is this defective?
A. It depends. There can be many causes to that type of strobing effect. Most of the time, it occurs on new ballasts, and will go away after a few days. If it persists, then it could be a number of things, such as a bad ballast, or incorrect ballast. Give us a call at 877-995-2677 if it doesn't go away after a few days, and we'll do our best to help you out!
