This 4 watt UV lamp features both long and shortwave ultraviolet bulbs. The dual short/longwave UV lamp enables checking for fluorescence; detects dyes, oils and assembled stones; and helps to distinguish natural stones from synthetics. Works with viewing cabinet (GMCC-10) or open stand (GMUVJ-124), both available separately. We strongly recommend the use of the UV protective eyewear when using this product.
