About This Attention! The UVB light bulb does not produce noticeable heat, please use this UVB reptile light in combination with a reptile heat lamp for higher heat output. High-Efficiency UVB/UVA Output - This 5W reptile lamp combines 2 specialized UVB LED + 6 UVA LEDs + 4 white LEDs to deliver 10% UVB radiation - ideal for Ferguson Zone 3-4 reptiles requiring moderate UV exposure. The 3-spectrum synergy ensures proper D3 synthesis while maintaining visible light brightness. Tested to provide 60-100μW/cm² UVB at 12' distance, meeting requirements for species like Bearded dragons. Durable Lifespan - Engineered with aluminum housing and advanced heat dissipation channels. It outperforms standard reptile bulbs by 300% lifespan. Energy-efficient LED technology consumes only 5W power while eliminating frequent bulb replacements - perfect for 24/7 bioactive terrariums. Eye-Safe 4000K Warm Lighting - The 4000K neutral-white light (CRI>85) replicates dawn/dusk conditions, gentle enough for light-sensitive species like crested geckos and ball pythons. Unlike blinding blue-toned LEDs, our full-spectrum design prevents retinal stress while maintaining natural circadian rhythms. Combined it with a Heat Lamp - This UVB light bulb is not generating the heat. Low-heat LED design (surface temp
