It's equivalent to a 1000w incandescent light bulb, and it's super useful for video work as it has a daylight colour temperature and doesn't use PWM for dimming. There are 900 individual LEDs in this panel, which is why it's so bright.

How do you easily and reliably manipulate a URL string programmatically? Do you use regular expressions or other kinds of string manipulations? Given all the ways to encode data in a URL, how do you ensure it remains syntactically correct while doing string manipulation? Manipulating URL's with regular expressions is rather difficult because of the format and nature of a URL. It's better to manipulate a URL as if it's a data structure, to let software easily change URL fields while ensuring the URL is syntactically correct.
