Aqua Ultraviolet 15 Watt UV Sterilizer Replacement Lamp
Aqua Ultraviolet's 15 Watt UV Sterilizer Replacement Lamp is positioned as a market-leading, purpose-built option for aquarium lighting fixtures because of its long service life, consistent UV-C output, and reputation for durable construction—traits that justify its modestly higher price compared with generic alternatives. Compared with lower-wattage consumer lamps like the Coralife 9W and pond-focused bulbs like the Tetra 18W, this 15W lamp delivers a strong balance of flow-through sterilization and compatibility with freshwater and marine sterilizers, offering better long-term value for hobbyists seeking reliable pathogen and free-floating algae control.

Coralife Turbo-Twist 9W UV Replacement Lamp
The Coralife Turbo-Twist 9W UV Replacement Lamp is the compact, energy-efficient choice for smaller aquarium lighting fixtures and inline clarifiers, offering a low-cost, easy-to-install twist-base design that makes it attractive for budget-conscious hobbyists. While it cannot match the raw sterilizing power of higher-wattage options like the Jebao 36W or the Aqua Ultraviolet 15W, its lower upfront and operating costs make it a practical option for small tanks or integrated lighting setups where space and power draw are limited.

Jebao 36W UV-C Replacement Bulb
The Jebao 36W UV-C Replacement Bulb is the high-output, cost-effective solution for larger aquaria and heavy bio-load environments, delivering significantly higher UV intensity per bulb and a strong price-per-watt advantage over premium brands. This makes it especially appealing where throughput and aggressive algae/parasite control are needed—though users should factor in higher energy consumption and ensure their sterilizer housings are rated for the bulb's power and heat compared with lower-wattage, more conservative options like Coralife or Tetra.

Green Killing Machine 24W UV-C Replacement Bulb
The Green Killing Machine 24W UV-C Replacement Bulb targets hobbyists seeking a mid-range, algae-focused option that balances power and affordability; its 24W output is strong enough for moderate pond and aquarium clarifiers without the cost or energy draw of 36W bulbs.

The Tetra Pond GreenFree 18W Replacement Lamp is engineered specifically for pond clarifiers and GreenFree fixtures, offering dependable algae reduction in outdoor applications and broad retail availability that keeps replacement costs competitive.
