T-2 6400 K Aquarium Lights
Superior Performance compared to older Technology T5

T- 2 Aquarium Lamps and Fixtures

• Very Low Profile with a 7 mm Diameter and compact length
• Axial type Wedge base
• VHO/ 82 CRI
• 73 LUMENS PER WATT; for example the 13 watt 6400 K produces 950 lumens (73 Lumens per Watt) which is 70% more lumens per watt than most bulbs, making this one of the best planted aquarium lamps available for its size (as well as an excellent complimentary Marine/Reef Light)!
Even a standard T5 Light does not have this output per watt, only LEDs are more efficient!
*Bluntly, the highest output of useful light energy for aquatic life of ANY fluorescent light!
• The Newest Technology T2, the 3rd generation model #302; includes a rotating lens with built in reflector, a feature not available in T5 Fixtures!
• Now Available; Actinic Blue T2
• For freshwater OR saltwater use (excellent for SW zooanthellic/symbiotic algae growth), or even home lighting too for economical space saving healthy full spectrum lighting.
• A LOT of light from a very small lamp that takes up little space! In fact one 13 watt T2 produces as much light as two comparable 6400 K 15 watt CFLs (13 watts vs. 30 watts for the same light!)

As little as 1 to 1.25 watts per gallon for a planted aquarium is all that is needed from these T2 Lights!!
• 10,000 hour lamp
• Very low Heat Output from self contained/ballasted fixture
• Great for DIY applications in hoods where space is a premium!
• These T2 fixtures are great for retrofitting small hoods in aquariums with little space needing an intense plant light (or lighting a shelf of bettas), includes on/off switch

• Linkable; complete fixtures (each includes ballast) can be connected in series (end to end), or in parallel via connecting plugs that are provided with each fixture (no separate purchase necessary to utilize this feature).

• With linkable feature (INCLUDED) this is not only an inexpensive replacement for older style aquarium light fixtures, it is far superior to much of what is currently available including the older technology T8 (or even slightly older T5) fixtures/lamps.
• Lamp is protected and is easily changed (see the picture below which also troubleshoots correct lamp placement)

Picture (Below)Demonstrating Replacing or Re-Seating T2 Lamp (often the lamp gets unseated during shipping due to small contacts):

• For example, two of these fixtures linked together (forming a longer fixture with two lamps) would work well for most 60 gallon Freshwater aquarium OR for the same tank one could add two sets side by side for planted aquariums or even many saltwater aquariums (with reefs or high light requiring planted freshwater we recommend supplementing with AquaRay LED Lights).
Even a longer tank, such as a 6 foot aquarium can have 3 or 4 T2s linked together to make a superior upgrade from outdated T8 or T12 lights many freshwater fish tanks still employ, with an increase in useful light energy and a decrease in electrical operating costs due to vastly higher efficiency.
Please note due to the fragile nature of a lamp this small in diameter, lengths longer than 21 inches are not practical, which is why the linkable feature is so useful!

• Includes mounting brackets for shelf mounting as well. Easily mounted in hoods, canopies, or simply above the aquarium.
Mounting can also be achieved by adhering these light fixtures with silicone
• Includes "Built-in" Electronic Ballast, On/Off Switch, & Power Cord

*Please Note; A maximum of Four T2 Fixtures can be linked in one chain, with 2 or 3 achieving better results (too many fixtures in one chain can cause premature failure)

*Also; Do NOT over tighten the mounting screws to the point that the fixtures pull away from the contacts for the T2 Lamps as this can result in a T2 light that either does not work or is overly sensitive due to poor lamp/fixture contact!

• A must have for small planted aquariums or nano/pico marine aquariums, especially where space is a premium
