It does not use bulbs. The LEDs are a part of the housing (integrated).
This fixture provides 4000K color temp. and 4000-lumen output,offers bright illumination ideal for both residential and commercial spaces. https://images.homedepot-static.com/catalog/pdfImages/14/14bf4a92-f2ed-46ab-8043-8f96f6ca220d.pdf
Though I have not done that for my light, I believe you could add a pull switch. You could splice into the two power source wires to have the pull switch control the flow of electricity to the light. The pull chain switch could be mounted into one of the two end caps on the housing after drilling an appropriately sized hole for the switch.

I don't know why it would but I can't tell you that for sure because I use mine in the kitchen.
Don't know. Mine never cracked. Best Garage light I've ever purchased.

First, choose a lower color temperature, 2700 K or max 3000 K. Everything else looks UGLY. Then choose dimmable downlights, like 4 inch inch LED cans. Use multiple of them, to make it some interesting light arrangement. I have for example in my kitchen two sets of LED's down lights, one set with narrow angle LED spots, and then a 2nd set with a more continuous light coverage. Like when you are mopping or cleaning a kitchen, you want bright light so you catch all the dirt. But for normal living, dining and cooking, you should have task lighting with light accents in a kitchen. It brings out the food and the cabinets, the countertops etc. out much more dramatic!
No, it is not dimmable. We installed a dimmer but it only made the bulb flash so we had to uninstall it.
I would say NO.I have not tried it, but these linear LED fixtures have not been designed for dimming. As an electrical engineer I can tell you, that dimming LED's is very tricky. The best results is doing PWM (pulse width modulation) in the low voltage DC space. LED strips, (monochrome or multicolor) on 12 V DC or 24 V DC with special DC based PWM dimmers deliver the best results for LED dimming. Regulating a sinus wave AC line voltage through all these electronic local converters in the fixture or bulbs give unpredictable results. The LED's flicker, or you have a relative high minimum brightness, you can not solve this so easy like it was with incandescent and halogen bulbs. You are entering a tricky area, with unpredictable results!
