Reptile Systems New Dawn LED 10w E27 Plant Growth Bulb - Vertical Position

The RS New Dawn LED 10w is a dedicated plant growth bulb designed for vivariums and terrariums where live plants are part of the setup. Running at a true 6500K colour temperature, it delivers the cool daylight spectrum that drives photosynthesis effectively, making it a practical choice for keepers who want strong, healthy plant growth without separate horticultural lighting. The E27 fitting and vertical-position design make it straightforward to integrate into standard vivarium lighting fixtures.

Light Output and Spectrum

At 6500K, this bulb sits firmly in the daylight range — the spectrum that plant growth responds to most efficiently. With a colour rendering index above 90, colours appear natural and accurate under the light, which matters both for plant health assessment and for the overall appearance of the vivarium. Output exceeds 700 lumens from a 10W draw, delivering a genuinely useful level of brightness for planted enclosures.

Beam Angle

The 40-degree beam angle concentrates light into a focused column rather than scattering it broadly. This makes the RS New Dawn LED particularly well suited to taller or deeper vivariums where directed light penetration is needed to reach lower-level planting, rather than simply illuminating the surface layer.

Pairing with UVB Lighting

This bulb is built to work alongside UVB-emitting lamps, not replace them. Used in combination, it raises visible light levels and supports plant growth while your UVB source handles the UV requirements of the animals in the enclosure. For bioactive and heavily planted builds, running both is standard practice.
