Notice Type: Product Revision Change

Product Type: AL143

Change Notification Summary

In an effort to improve our products, Advanced illumination (Ai) will update the LEDs used in the AL143 design. This change will result in a brighter, more uniform light at the same price*. Customers may still buy the current revision of this model until August 5th of 2016. After that time, orders for these products will be converted to their respective AL143 Revison A models.

This LED change will result in additional wavelengths being available: 365nm, 375nm, 385nm, 405nm, 455nm, 505nm, 660nm, 730nm, and 940nm. Additionally the white LED color temperture will be changing from 6100K to 5500K.

*Pricing for IR wavelengths (730nm, 850nm & 940nm) will be reduced to the same price as visible wavelengths, while UV wavelengths (365nm, 375nm, 385nm & 395nm) will increase from $605 to $750.

Orders for customized (dash numbers) versions of AL143 will be honored until December 1st of 2016. Ai will be actively working with customers for those products to simplify the transition.
