text: Was relatively happy with the bulbs and the company. Until a few weeks ago, I would have rated them a 4 star. Although, I've had issues with a few of the bulbs - flickering or going dead after a few months. Which I can understand and live with as long as I can easily get replacements. Customer Service was eager to help but they seem to have issues with receiving and responding to the information requested in email. I have sent 5 emails with the same information to them, which they each claim to have not received and ask me to resend. This is email - it is pretty reliable. I am not receiving any email send failures/errors so something is obviously broken with their process or system. I'd like to stay with Hyperikon for consistency of look and light as I've already invested hundreds of dollars in their bulbs but between the issues with the quality of the bulbs and the frustrating experience with customer service, I will need to look at an alternative - maybe the Sunlite, they get a 5 Star rating.
