GE, 4 Pin, Non Integrated Compact Fluorescent Bulbs, 40 W, 4000K, Cool White

Biax™ L covers a range of single ended compact fluorescent lamps with high lumen output and are available in a wide range: 18, 24, 34, 36, 40, 55 watt versions.
The single ended design is less than half the length of standard fluorescent lamps. This makes Biax™ L the ideal choice for modular luminaires. The range is available in colours of 2700, 3000, 3500, and 4000K allowing use in most environments.
All Biax™ L lamps have a CRI of 82. The family of Biax™ L lamps offers a rated life* of 10,000 hours for 18W to 36W and 20,000 hours for 40 and 55W. The 40 and 55W versions are for use on high-frequency electronic gear only.

Typical application areas:
Compact size is ideal for modular luminaries in commercial premises, shops, offices and hotels.
Alternative use in non-general lighting applications such as task lights and sign lights.
The 34W lamp offers an economical alternative to the 40W from an installation point of view while having the same physical dimensions. It is essential to use suitable electronic gear, or electronic starter when operating the 34W lamp with conventional gear.
The 40 watt lamp has been specifically designed for optimum performance when used with high-frequency control gear.
The 55 watt lamp offers 4,800 lumens in the same overall length as the 40 watt, ideal for use where higher lumens
are required.
