GE bulbs are great. You can go to their website and check out the spectrum details. Got all for $1 or less or free.
I’ve never had a CFL blow, used them for years, but mostly in the warm months only.
Also have almost 50 incandescents, Rite-Aid was giving away GE’s free after rebate. I use them during heating season.
No significant difference in the spectrum, check the GE site.
I’m pretty sure ours are GE, there is a painfully obvious difference in the spectrum especially when you first turn them on. They lack brightness and make you think one of the bulbs is out. Thankfully 1 has already died. There is quite simply no way I’m ever buying a CFL again, they are bad lightbulbs, I don’t care if I have to smuggle in my A15s from Mexico. Ounce bitten twice shy.
