Review on Sunlite PLD13/SP65K/10PK: 6500K Daylight Fluorescent Twin Tube CFL Bulbs (10 Pack) with GX23-2 Base by Maya Allen

For me these lamps are not acceptable. They blink, blink, blink, blink, blink. Lightning . . . and then finally switch on - like fluorescent lamps 50 years ago. I bought it to replace a different brand lightbulb in plumbing (that brand no longer makes the lightbulb). The lamp to be replaced was 15 years old and turned on immediately. So it doesn't look like these lamps should do that. I didn't think anybody would make fluorescent tubes that still have a flicker, flicker, flicker problem. I hope the seller takes them back but in any case I will not use them and will buy another brand.
