Satco S8320 4100K 13-Watt GX23-2 Base T4 Quad 2-Pin Tube for Magnetic Ballasts, Cool White

It works well, it’s bright white, I couldn’t find a soft white, so it’s bright light typical fluorescent lighting.

This worked perfectly for my NuTone bathroom fan - it blinks a couple times when you light it up, but that's normal for CFL bulbs. I was a bit concerned because it fluttered a bit after being on a while when I first turned it on. But I turned it off, turned it back on, and it's been fine ever since - just the usual initial blink, and then it burns solid.

Popped right in!! I wasn’t sure which model to get - but this worked. Thrilled.It does blink when you turn it on - like more fluorescent lights, but I kinda like the vibe for my new kitchen light.

As long as you carefully check your pin alignment is the same as these bulbs have you’re good to go. Easy to I stalk and work for years. But I prefer LED now.

I dunno what the issue is, it's the right size and shape, yet I can't close the casing while the bulbs are in. I'm a pretty logical person, I've given it much, and thorough inspection, something's off on the plastic outer edges of them that's causing them to be a fraction of a millimeter too long, causing the casing of the light not to fit. Aside from that, great color and brightness, though that is an issue lol.

CFLs are supposed to flicker upon turning on, but these continue to flicker when left on for several minutes-- very poor quality

it worked in my bathroom fan/light combo and was a few bucks cheaper than the name brand. hopefully it will give me a few years of light.

Fits perfectly and even brighter than the original.
