it came, it turned on, it shined light...it said for "flowering and fruiting"
And thats exactly what happened after a few days of using it on some of my house plants
These plants would ONLY flower outside on my porch during the summer months
Its kinda neat to have flowers in October
Note it is an extremely heavy unit, the heat sink seems to be of some plastic/ceramic hybrid and you will probably only be able to use a strong clamp shop light to keep it up right
This bulb weighs, literally, over a pound. Be sure you can hang it over your plants--- it drags the head of a regular work light straight down. I can't use it because of the weight.
