Ordering Part Numbers
The table below lists ordering part numbers available for XBT-3535-UV LEDs. The part number includes a bin kit, a group of flux and wavelength bins described in page 2, that are shippable for a given ordering part number . Individual flux or wavelength bins are not orderable . Flux bin listed is minimum bin shipped – higher bins may be included at Luminus’discretion.
