Product Overview
LuAG-4056 is a high-performance lutetium aluminum garnet (LuAG)-based yellow-green LED phosphor specifically designed for warm white lighting applications. With a peak emission wavelength precisely positioned at 540nm, this phosphor delivers exceptional luminous efficiency when excited by 455-460nm blue LED chips.
Featuring an impressive 111.18% relative brightness and a dominant wavelength of 566.7nm, LuAG-4056 achieves outstanding color rendering performance with Ra>80. The 12.5μm particle size design combined with ultra-broad spectrum characteristics (FWHM 109.4nm—the broadest in the LuAG series) makes it ideal for warm white lighting, healthy lighting environments, and commercial display applications requiring superior light quality and warm color tones.

Frequently Asked Questions (FAQ)
❓ What makes LuAG-4056 different from other LuAG products? LuAG-4056 has the longest dominant wavelength (566.7nm) and lowest CCT (4224K) in the series, suitable for warm and comfortable lighting. Its 109.4nm FWHM is the broadest, ideal for high CRI applications. | ❓ What CRI level can be achieved with LuAG-4056? When combined with deep red phosphor, LuAG-4056 can achieve Ra 85-90 for high CRI warm white light. Standard warm white configurations achieve Ra 80-85 with excellent color reproduction. |
❓ What red phosphor ratio should be used? For high CRI warm white (Ra>85): LuAG-4056 60-70%, red phosphor 20-30%. For standard warm white (Ra>80): LuAG-4056 70-80%, red phosphor 15-25%. Contact our engineers for detailed guidance. | ❓ Do you offer small-batch samples? Yes.
