I found some more info on the light. According to a few sources, the color temperature is 18,000K. This would mean that this bulb is good for vegging, not optimal for flowering. You can certainly use it for flowering, just not sure it is your best option.

BTW, what is the wattage of the bulb?

I see they come in 8,14,15,20,25,30,36 and 40 Watt varieties. The 30 Watt variety is 1660 Lumens. If you want to grow optimally, each plant should have 2,500+ lumens. More for flowering. So I guess my point is that it may take a lot of these bulbs to grow just one plant. Just something to consider.

Good luck.
