lumenivo 13 Watt Quad Tube Fluorescent Lamp with GX23-2, 2 Pin Base 2700k Warm White U Shaped Compact Fluorescent Bulbs 2 Pin - PLC 13w 2 Pin Double Tubes CFL with 810 Lumens Output - 4 Pack

Use these in our bathroom air vents. The fixtures are about 20 years old and still going strong so I’ll just keep buying these bulbs yearly.

working fine as replacement for what we had. NO issues seen so far.

The color is similar to LED, not perfect, but the best I have found

The media could not be loaded.  This was the first time we replaced these bulbs. Tried these and horribly flickered (see video). Returned them and subbed for a common namebrand at the big box. No problems with those.

Item as described, affordable, and fast shipping.

I had one light blow so got the four pack and replaced at three with one spare. Knew other three will blow soon. Price was awesome. like that packaging was minimal and no wasted excess like in a retail store.

This little bulb added an immense bright light.

You really don’t want to waste your time or money on these. Just bought a 4-pack to replace 2 Panasonic CF lights in our shower room light/fan. Others have complained about this; I did not read the reviews this time. Silly me.Don’t be tempted by the price (about half what you’ll pay for Panasonic at Lowes or Home Depot). At minimum, choose another product on Amazon, or risk wasting time with a return at best, or burning your house down at worst (based on others’ reviews that after they do light up, at least some of them become blistering hot).Amazon take this product off of your “preferred purchase” list. It’s not becoming on your reputation….
