904530 , Large

The was my first Adjust-a-Wing and without this spreader, I would have devastated my plants. The large one kept the plants below it from burning, but I would suggest being careful to in-door farmers trying a light like this the first time. It tosses a lot of heat my other lights are cooled and vented this one cannot. I would suggest being careful where direct lights hits plants where the spreader does not diffuse I burned a couple of plants "learning" what not to do. The light works fantastic provided you maintain a well ventilated space with the temp 12 inches below the lights does not exceed 85, preferably 70-80 and humidity 50-65%. I place ionic misters to keep a constant flow a cool mist on plants closer to the bulb. The results are well worth the added effort,

Took about 4-5 days for them to ship it but once they did, it came here to Alaska quickly. I ordered the large and it was substantially larger than i was expecting.Very pleased.

These do work! Must have!
