## Questions & Answers

**Q: Are these led lights dimmable?**
A: The cords have an on/off rocker switch built in.  Generally this style of LED is not dimmable.  Each is individually not that powerful.  I am adjusting the intensity by adding and subtracting tubes and adjusting the height over the plants.  It is working out fairly well.  For an 18" x 48" shelf I am using 3 tubes.  I just used these this season for seed starting and those plants were just put in the garden.  They worked well.

**Q: How many lights and what distance for sowing seeds for 48"x24" flats?**
A: We do not use them for seed flats at this time but will likely do so next spring,  These are very bright, powerful lights.  I would use no more than two 48 inch per flat.  Not knowing your location or setup I do not think that these bulbs will generate enough heat without other supplemental heat.

**Q: How far apart in parallel should the lights be placed for growing seedlings?**
A: The height would also need to be considered as for spacing in parallel.  12 to18 inch for approx 12 in height

**Q: I bought a six pack of 2' lights. the shelf is 16" x 36". How many 2 foot lights per shelf?**
A: I turned my walk in closet into a nursery. I have 3 long shelves around 4’ in length and 2.5’ in depth. I use 2 lights per shelve. That’s been working for me.
