The 300-II LED Variable-Color On-Camera Light is one of a series of on-camera LED lights from Yongnuo Digital. This compact, 3200–5500K tungsten/daylight-adjustable unit offers two dimming modes (rough and fine), an IR remote control, four barndoors, a power-on/luminance adjustment knob, and four filter panels. Up to eight lights can be grouped via the IR remote control.

Designed to work with most DSLRs and small camcorders, the 300-II LED Variable-Color On-Camera Light can be powered using a Sony NP-F series battery (not included) or an optional AC adapter (not included). A push-button LED status bar shows the remaining battery power. A 5800mAh NP-F battery (not included) will power the light for up to 130 minutes. The 300-II LED Variable-Color On-Camera Light has three mounting options to your camera via a hot shoe, on a flat surface using the mini plate, or handheld using the included handle.

Q: 4. can i use this with a canon camera? also can this ring light height be adjusted to go up and down??

A: You will not be able to mount a Canon Camera in this ring light, but you could certainly use it as a key or fill light without a Smart Phone in the light. The height adjustment does not go straight up or down, but you can adjust the goose neck.

A: This light can be powered via Sony NP-F series batteries or an optional AC adapter. Neither of these are included in the box, but there are plenty of options on the B&H website. For example: AC Power Supply: https://bhpho.to/3jmevww Watson NP-F770 Battery Kit: https://bhpho.to/3rdi4HU

Q: 9. how many and what kind of batteries does it need?

Q: 10. What's the CRI ?

A: In addition to the answer already here, the higher the number the better the light on the CRI value. This light is supposed to have a 90 or greater CRI value. I've seen several spec sheets that claim 93 and some 95 . Generally a high end and well-calibrated spectrometer is the only way to know for sure with each light that you own. At this price point, I'd go for the 90 value in terms of guessing;-) They are nice lights though, especially for dollars expended.
