These Daylight bulbs are great, bright yet has a soft light. I could not find this size in any big box store or electrical outlet, in fact was told they don't make this size with Daylight bulbs. Thanks Bulb.com keep making them.

So glad you offer this product in the daylight and hope you continue to carry it. Every place I use the daylight tubes makes the room and interiors come to life with true color and no awful yellow glow which is refered to "soft white", which to me is more like soft yellow. Also my mother has macular degeneration and it seems the daylight help her distinguish true colors. Please never stop offering daylight products. Your service and delivery were excellent. It only took like 2-3 days to get the product.
