LED chip ultra blue 2 W / 12 V replacement lamps, sera SE-31180, pack of 2

The sera LED chip ultra blue 2 W / 12 V replacement lamps are compact blue-spectrum light sources designed for aquarium and small low-voltage lighting applications. Each lamp delivers 2 watts at a 12 volt rating, and the pack contains two identical chips. The ultra blue output is intended to accentuate blue tones in aquatic environments and support visual contrast for corals and fish while fitting into existing 12 V fixtures that accept LED chips of this form factor.

Advantages

These replacement lamps provide narrow-spectrum blue illumination with low power consumption, allowing for longer operating times on low-voltage supplies. Their compact chip design simplifies installation in compatible fixtures and reduces heat generation compared with higher-wattage sources. Supplied as a pair, they offer convenient redundancy or dual-point lighting without requiring additional purchases.

Suitable for

• Aquarium accent lighting to enhance coral and fish coloration
• Small aquatic systems and nano tanks
• Low-voltage lighting projects and retrofit of compatible 12 V fixtures
• Supplemental blue spectrum illumination for plant and coral display

Key specifications

• Light colour: ultra blue spectrum suitable for aquatic accent lighting
• Power consumption: 2 W per chip
• Operating voltage: 12 V DC
• Quantity: pack of 2 identical LED chips
• Form factor: compact LED chip designed for replacement use in compatible fixtures

How to use

Install each LED chip in a compatible 12 V fixture or retrofit housing that accepts this chip form factor, ensuring correct electrical connections and polarity. Verify that the fixture and supply can safely deliver the 2 W load per chip and that any existing heat-sinking or mounting accommodates the chip’s thermal output. Power the lamps with a suitable 12 V DC driver or transformer and test operation before final assembly of the lighting unit.

Usage recommendations

For aquarium applications, position the ultra blue chips to provide even accent lighting without causing intense localized hotspots. Use in combination with broader-spectrum white or full-spectrum LEDs when a balanced overall light is required for plants or corals. Observe fixture temperature during initial operation and ensure adequate ventilation or heat sinking to maintain longevity.
