About HPSLight.com
The definitive resource for High Pressure Sodium grow light information.
Our Mission
HPSLight.com was created to fill a gap in the indoor growing community: a trusted, unbiased resource dedicated specifically to High Pressure Sodium lighting technology.
While LED technology dominates the conversation, HPS remains a proven choice for countless growers worldwide. We believe growers deserve accurate information to make their own informed decisions rather than being pushed toward any particular technology.
Every specification on this site is verified. Every review is based on real-world experience. No sponsored content, no hidden agendas.
What We Stand For
Verified Information
Every product specification is manually verified against manufacturer data and real-world testing. No copy-paste specs from Amazon listings.
Honest Comparisons
We acknowledge both the strengths and limitations of HPS technology. When LED is the better choice for a specific situation, we say so.
Community-Driven
Our content is informed by real discussions from growing communities. We listen to what growers actually need, not what manufacturers want to promote.
Education First
We prioritize helping you understand the technology so you can make your own informed decisions, rather than just telling you what to buy.
