This light more than adequately meets those standards. The quality matches the price. Great customer service.

Use these lights to start seedlings during the late winter. At the moment i have over a pot that i placed a red potato that had some eyes in it and planted it. My plants are very happy and i see veggie yields and flower blooms in winter.

Many businesses do this trick as a ploy. There is no ul label which is another lie being told (the ul white book says the label must be on the light if claiming ul certified) the spd chart on amazon is also a lie.

When set to run for 12 hours, the light shuts off and does not come on the next day. This defeats the purpose of the timer feature.
