The 2213194-1 is an optional accessory, specifically a Model 1 reflector optics retaining clip for the LUMAWISE Type Z50 LED holder. This clip is designed to provide a secure mechanical attachment for secondary optics from LEDIL, particularly the ANGELA and ANGELINA series reflectors. It is used with the Z50 holder (part number 2213130-2) to complete a solderless lighting assembly for Sharp Mega Zenigata LED arrays. This component is crucial for applications like spotlights, downlights, and architectural lighting that require precise beam control using LEDIL reflectors.
