Thank you for inquiring about the Oversized Utility LED Light Bulb # T100/4000/5K/LEDHDRP. Our apologies. This LED Bulb is not intended as a Grow Light Bulb. The bulb has CCT of 5000K Daylight, but it is not intended to substitute for sunlight when growing plants indoors. This oversized bulb has high output bright LEDs that are meant to light up large distances in barns, garages, backyards and work areas that require a lot of light.
Thank you for inquiring about Model # T100/4000/5K/LEDHDRP. This bulb is just under 4 inches wide so it can fit in 4 inch recessed cans.
Thank you for inquiring. The screw-in base is actually the common E26 base, which is also referred to as the standard or medium base
in my humble opinion, a garage can never be 'too' bright. But then I always go for more power, lol, but still, I truly don't think anyone would think 2 of these would be too much for a standard garage. They really put out a nice white light, very nice. Go for it!! Heck, lol, make it 4, can never have too much.
