Ordering Part Numbers
The table below lists ordering part numbers available for XST-3535-UV LEDs. The part number includes a bin kit, a group of flux and wavelength bins described in page 3, that are shippable for a given ordering part number. Individual flux bins are not orderable. Flux bin listed is minimum bin shipped – higher bins may be included at Luminus’discretion.
