Comments about Bulbrite 28 Watt, 46 Inch T5 Daylight White Fluorescent Bulb:

I used these 6500k bulbs to replace the 3500k bulbs that came in my [...] 48" T5 lights. (3500). My plants are doing much better with the blue light. They are now healthy and growing fast. These bulbs appear brighter than the [...] bought bulbs too. Electric bill per lumen is really good but startup cost is high because you need alot of lights to get bright enough light to grow plants indoors. Once you have enough lights it will be bright, even light and the bulbs stay cool. In a 10 foot square space I have 11 fixtures (22 bulbs). I grow oranges, lemons, dwarf apple tree, blueberry, and banana plants. - I live in Massachusetts.
