Low Heat Lighting Solutions for Modern Data Centers

How Do You Retrofit Data Center Lighting Without Disrupting Operations?

In a data center, power is reliable and backup systems are in place. Cooling is carefully designed to keep everything running smoothly. Security is layered to protect assets. However, lighting can sometimes be overlooked until a bulb goes out during a maintenance window or a technician finds it hard to read labels in a dim aisle. That small delay can end up costing more valuable time.

Over time, fluorescent tubes gradually become dimmer and need ballasts that can eventually wear out. HID fixtures tend to get quite hot and need more regular maintenance. Every maintenance session requires staff to be in controlled environments, which can sometimes cause disruptions. Taking a moment to plan these updates can help keep everything running smoothly and safely.

Modern data centers operate in precisely controlled environments, featuring hot-aisle/cold-aisle configurations and raised-floor air distribution. Temperatures are carefully regulated, and airflow is deliberately directed. These facilities are characterized by high equipment density. In such settings, lighting must produce minimal heat, be long-lasting, dependable, and provide a uniform appearance across extensive rows of racks.

Switching to high-performance LED lighting boosts reliability and efficiency. Bright, glare-free lighting speeds inspections, cable tracing, and rack identification, and enhances safety. Well-lit aisles help technicians work confidently. Great lighting is vital in precise environments.

Lighting in Hot Aisle / Cold Aisle Environments

Hot aisle/cold aisle setups boost cooling by separating intake and exhaust air. Cold aisles supply conditioned air to servers; hot aisles return air to cooling systems. Raised floors distribute air beneath servers via perforated tiles. Lighting must work evenly in both zones, avoiding reflections or hotspots on glossy panels.

Low-heat lighting solutions help support cooling strategies rather than working against them. LED technology produces significantly less heat waste than fluorescent or HID sources, and high-quality products are designed to operate efficiently across a wide temperature range.

HyLite’s OptiMax LED tubes are specifically engineered to run cooler than fluorescent tubes, making them well-suited for enclosed fixtures in conditioned environments.

OptiMax Tubes for Data Hall Aisles

Most data halls use linear fixtures to illuminate long, narrow aisles between server racks, making them ideal candidates for LED tube retrofits. Upgrading these fixtures with a flexible, high-performance LED solution allows facilities teams to improve visibility, reduce maintenance, and simplify standardization across the entire space.

HyLite’s OptiMax LED tubes are designed specifically to make that transition efficient and reliable. Here’s what makes them well-suited for critical data center environments:

• Selectable wattage (12W, 15W, 18W) to fine-tune brightness based on aisle width, ceiling height, or task requirements
• Multi-CCT options ranging from warm to daylight tones to optimize clarity in operational areas and comfort in support spaces
• Ballast bypass (Type B) operation that removes a common failure point and improves long-term reliability
• Up to 50,000-hour rated life with a five-year warranty for reduced maintenance exposure
• Multi-Mode version available for phased upgrades, allowing either ballast-compatible or direct-wire installation where rewiring must be staged

Arc-Cob Lamps for High-Output Zones

While linear LED tubes cover most data hall aisles, certain areas require higher output and greater durability. Electrical rooms, mechanical spaces, staging zones, and select support areas often need stronger illumination and greater flexibility in beam direction.

HyLite’s Arc-Cob LED lamps are built for these higher-demand environments, offering performance and protection where it matters most:

• 350-degree rotatable base to adjust beam direction, reduce glare, and improve uniformity in irregular or higher-ceiling spaces
• High-output options (including 100W models) designed to deliver strong lumen performance with excellent efficacy
• Universal voltage compatibility up to 347V AC for flexible integration across facility power systems
• IP-rated construction for enclosed fixtures to support reliability in controlled yet demanding environments
• Integral surge protection and durable thermal management to help safeguard against voltage fluctuations and heat stress

Low Heat, Long Life, and Lower Risk

The term “low heat lighting solutions” describes a practical benefit.

Every watt of inefficient lighting ultimately becomes heat. While lighting accounts for only a fraction of the total data center load compared to IT equipment, inefficient fixtures still add unnecessary strain to cooling systems. Reducing that waste improves overall efficiency and supports environmental control strategies.

Long lamp life decreases maintenance, minimizing disruptions and allowing technicians to focus on infrastructure rather than lighting failures.

Get A Data Center Lighting Strategy

A successful data center lighting retrofit begins with documentation. Identify fixture types by zone, confirm voltage, note mounting heights, and determine where sensors or constant illumination are required. Standardize product selection across similar environments to simplify future replacements.

For linear aisles and corridors, OptiMax tubes provide a consistent and flexible platform. For higher-output or specialty areas, Arc-Cob lamps offer strength and directional control.

Sensor integration should be intentional. OptiMax supports occupancy controls, making it effective in intermittently occupied support areas. Avoid unnecessary dimming complexity and follow installation guidance carefully, especially regarding ballast compatibility verification.

Phased upgrades are often practical. Begin with high-maintenance zones, then expand standardization across the facility during scheduled maintenance windows.

Why the Time is Right for an Upgrade

Energy efficiency standards and facility expectations are rising as IT density increases. Outdated lighting undermines efficiency and causes service events. Switching to modern LED lighting reduces maintenance, aids cooling, and improves visibility.

OptiMax tubes deliver flexible, long-life performance for data hall aisles and support spaces. Arc-Cob lamps deliver higher output with directional precision and durable construction. Together, they form a reliable foundation for important facility LED lighting.
