gasrocks said:Welcome. Where do you live? A clamp light in a reflector is not expensive but only covers a small area. 4' x 2 shop lights with regular bulbs can be gotten usually for $10 and does OK. You want your lights on a timer and set for 12 - 16 hours a day, every day of the week. No inexpensive set up will put out enough light to do any damage to the contents of the room. You say for the summer. Most people ask this same question in regards to the winter. Many new LED fixtures out there that can do well, last a long time but have a high initial cost. I winter my house plants under 6500K T5 HO lamps. Can you find a secure place outdoors in the shade for your plants? Gene

The more wattage the better. Without getting into technical explanations, look for a color temperature that is 5,000+ K.
Keep the lights as close as possible to the plants and leave them on for 8-12 hours per day.
The lights will not cause permanent damage to fabrics, but they may cast a strange color in the room while they are on.
