Ok LED bulbs conform to the description ... But ... I'm a little scared at the whistle which is produced at the base of each pellet of these bulbs ... This is I think obviously the embedded processor. .. This is still 220V .... Anyway I received a first order but the two bulbs sallumaient not at all. I think they have been damaged or other during transport marketplace ... Seller is very honest and responsive he returned relativementrapidement two spare bulbs which they operate. But always this unpleasant whistle that worries me a little. After the price and performance There are no magic. I put 5 stars to the seller and Amazon to the accompaniment of HS replacement bulbs. For efficiency bulbs for horticultural use extra .... That remains anecdotal. To be used on cuttings or clones seedlings after it is far from efficient light ... Normal Go sincerely seller Ok ok product and Amazon ... Thanks ...
