Very Well Packed and Arrived in Perfect Condition
I have ordered other florescent in the past and they always arrived broken, but these were in a cardboard tube, wrapped in bubble wrap and the tube was in a box. Although the tube of was loose in the box, it should have been secured in the box with peanuts or bubble wrap, all arrived safe and put four right to work. I bought these for my kitchen and not to grow anything. It might be me, but the color these lights emit does not seem correct to my eyes and 5000k LED light I have over my sink seems to be whiter as seen in the pictures. Very little change when I take the diffusers off the light fixture; they are brighter, but not as white. These seem to give off a tint other than white, maybe a green or blue, and I guess I am going to have to live with that until I buy some LED bulbs to replace these. Just got them so how long they will last is unknown, but when I first turned them on I left them on for 12 hour straight.Changed my mind and cannot deal with the green tint of my kitchen so going with new light fixtures with LED. Cannot stand the green look of my kitchen.
