Maximum Placement Distance: 46"

Usage Guidelines:

We highly advise pairing this bulb with a Solarmeter 6.5 to ensure your reptile receives the correct UVB levels.

Always use a wire lamp fixture rated for a minimum of 275w to avoid overheating risks.

Given its intense UVB output, this bulb is ideal for spacious enclosures (at least 48" in height). Be sure to understand your reptile's specific UVB needs and adjust the bulb's distance from the basking spot as necessary.

You might need an extra halogen heat source or UVB lamp to achieve the ideal temperature or UVB gradient for your pet. Regularly monitor the basking area's heat and tweak the distance between the fixture and basking spot to ensure a safe thermal gradient. ALWAYS double-check the basking spot temperature to prevent any risk of burns to your reptile!
