Hello and welcome tec111,

They are good, and at 6400K and 54watts with abt 5,000lumens they could be fine for vegging, even 5 plants.

But, they do not come with reflectors, and that could be important, depending on how you mount them. I used 5 of those over my clonner/seedling area. 4 of them I added reflectors (ice cap brand) and in 1 I substituted a actinic white (very blue) for 1 6400K bulb.

here's a pic or 2.
