My 300w wonderlight is NOT so WONDERFUL any more. Purchased in January, began using this bulb in mid May, not working and its been used less than 90 days. Product works but how many units are defective and will prematurely stop working before the rated 10, 000 hours +???....the product has a weakness, its filament is not of a quality that stands up to the products long term application, as stated, in my opinion. Fortunately it is covered by warranty, but at a cost to the plants, my day, time and effort, not to mention the return process and what to do with my plants because its Saturday morning. The plants will deteriorate by the time the new light arrives, not good. I am skeptical if these bulbs can actually perform for the rated hours they claim they will.
Decided to order a Wonderlite to try to overwinter a meyer lemon, but found very few places that sold them. Took a chance on ordering from Orchidlight as I hadn't heard anything positive or negative about them, but am pleased I did. Ordered in the evening on a Wednesday and received the light well-packed and shipped 2 days later. Definitely recommended.
