2G11 DULUX Quad Tube Shape CFL Bulb, 40 W, 4000K, Cool White Colour Tone

OSRAM DULUX L lamps are non-integrated compact fluorescent lamps with high luminous flux. They have almost the same luminous flux and power consumption as tubular fluorescent lamps but are less than half as long and are more compact than U-shaped and ring-shaped lamps. OSRAM DULUX® L are the ideal light source for modern space-saving wall and ceiling lighting in offices, shops, exhibition rooms, foyers and canteens. They are also used for display and outdoor lighting.

OSRAM DULUX L 18, 24 and 36 W lamps can be used with conventional control gear or appropriate electronic control gear, such as QUICKTRONIC®. These lamps can also be dimmed in conjunction with suitable electronic control gear.

Fluorescent Lights are used when you require, clear consistent light for any environment. It reduces the costs compared to Incandescent lamps with very little maintenance. Fluorescent tubes are the ideal light source for large work areas due to their energy efficiency and minor heat production. Some areas you can use fluorescent lights are:
• Offices
• Public Buildings
• Shops
• Supermarkets
• Hotels
• Restaurants
• Warehouses
• Car Parks

How much power do Fluorescent Lights use?
On average LED’s use 60% - 70% less power compared to incandescent bulbs. An average fluorescent bulb which provides 800 lumens will use only 13 to 15 watts compared to a similar the incandescent bulb which uses 60 watts.

How long do fluorescent lamps last for?
The average life of a fluorescent light bulb is from 7,000 up to 15,000 hours. This is 8-15 times longer than life of incandescent lamps which is usually only between 750 – 1000 hours.

Compact Fluorescent Lamps

Energy saving of typically 75-80% when compared to GLS lamps of a comparable light output
Long life, 10000 hours typically, which equates to lower maintenance costs
2-pin versions have integral starters and should only be used with switch start ballasts
4-pin versions are designed primarily for use with high frequency ballasts or in emergency lighting applications
Triphosphor coatings give good colour rendition: Ra 80 to 89
Choice of colour temperatures
