FINCHforum

My previous f. tube was 910 lumens. 5000k 98cri. Seems it is discontinued.
However i don`t know anything about the lumens except each lumen is equal to one candle light lol.

Do you think this is a good choice for finch flight cage lighting?

Color Temperature: 5,000K
Average Lifetime: 20000 hours
Lumens (light output): 2000
CRI: 98

5000k should work well

Here's an article that explains lighting for birds very well
https://mickaboo.org/confluence/downloa ... ummary.pdf
In the lighting reference section it says 400 lux is the min. over 1000 is recommended.
"ADEQUATE BRIGHTNESS
Try to provide 400 lux as a minimum, 1000 lux or more is preferable. It is highly unlikely that your setup will be too bright. 10,000 lux, which would be nearly impossible to simulate, is acceptable. However, also provide an area that is shielded from light, by hanging a towel over a corner of the cage or placing a large (bird-safe) floor-plant behind it. "

If you want to go into it more here's a link to the difference between Lux and Lumens
