Hello, I have a four-foot four bulb grow light I no longer need, with five new T5 HO, (high output), 6500K bulbs. I ordered the new bulbs from Walmart.com and they had a sale on a five pack so I figured what the heck and extra bulb can come in handy. Asking $120.00 or best offer. For a quicker response call or text, I only receive e-mails on my PC and it's not on every day. Thanks for your interest and have a nice day.
