if i purchased this light, http://www.bigalsonline.com/BigAlsU...6/cl0/coralifefwt5aqualightdoublestriplight36, would i be able to upgrade the light bulbs to a higher wattage or would i only be able to use 21watt bulbs
yeah thats how it is. as the K rating increases, you get more color and less light outputtimeneverfreezes;2667370;2667370 said:I believe the Kelvin rating on the bulbs is a measure of color output not necessarily light output which would be lumen's. I think the higher the Kelvin rating the lower the lumen output but i could be wrong.
