Topic: Can any engineers or lighting experts help me?

I'm looking for a very specific type of light bulb. It must be an LED bulb, with a GU10 socket, with between 300-450 lumens, and (this is the most important part) it must have a color temperature between 4000K and 5200K or so. The problem I'm having is that all the GU10 LED bulbs I can find either have a color temperature of 3000-3500K (way too yellow), or 6000-7000K (way too blue). I need to achieve the most natural light possible, so something a little over 4000K is ideal, but a little bit of blue is OK, so something around 5000K would still be great.

Close, it's for a jewelry display case. The lights we use now are way too yellow, and consume about 10 times more energy than an equivalent LED bulb, and LED bulbs last about 10x longer. I need GU10 bulbs because the current fixtures use this type of socket, so if I can find a bulb that meets these requirement, it could save us thousands of dollars when compared to switching over to an entirely new LED fixture system, as well as save us about $500 a year on energy costs, boost our jewelry sales, and we'll probably never have to change another bulb again. Plus the current bulbs produce a lot of heat and it gets uncomfortable.

Yep, until I go to the gym in an hour or so. Then after 4 or so I'm free for the rest of the day.

What I might end up doing is mixing bulbs. The fixtures are close enough that I could alternate between 450 lumen 3500K bulbs and 360 lumen 7000K bulbs which would give me about a 5050K average, but I'm worried it will end up being a bit splotchy. It's not ideal.

First one is only 145 lumens, second one is an AR111, not a GU10. (I stand corrected, it is a GU10 but I can tell just by the picture that it will not fit in the fixture.) I think next time I'm at work I should get the exact specs on the bulbs we're currently using. That might help.

Yes, you did, thank you. I just wanted to let you and anyone else who might be able to help know why those won't work.
