Customer Reviews

Literally, within days we noticed an improvement in the colour of our Chameleons.
Rob Scales and Fangs Essex.

I wouldn’t use anything else at this point! My terrariums are brightly lit and the bromeliads are retaining their natural ‘sun grown’ color under these lights.
Dr. Shawn Harrington

The light and Shade method explained

Historically, keepers have been advised to buy a lamp corresponding to the length of the enclosure. More often than not, these lamps were used…


Offering a significant increase in both visible light and UV output compared with T8 lamps of similar length.

  • For Forest Species
  • 6% UVB for the synthesis of vitamin D3
  • 30% UVA
  • Produces excellent natural colours
  • 200%+ more visible light than equivalent length D3 T8 lamp (un-reflected)
  • 80% more UVB than equivalent length T8 lamp (un-reflected)

The Benefits of T5 Technology

  • Smaller diameter lamp – 5/8 of an inch (16mm) compared to 1” (26mm)
  • Flicker free – all T5 lamps operate on efficient, high frequency ballasts
  • High output T5 lamps are especially useful for captive reptiles. The extra power that these lamps provide will help a keeper to generate a good UV gradient and provide safe basking quantities of UV over a much wider and deeper area.

  • Mix n Match

    The Arcadia D3 T5 lamp can be used in conjunction with either the Arcadia Original Tropical Pro or Freshwater Pro High Output T5 Fluorescent lamps to encourage good plant growth.

    T5 Original Tropical Pro and T5 D3+ Reptile 12% UV Fluorescent Lamps

    “I was persuaded to give the Arcadia T5 lighting range a try. From the moment they arrived I was absolutely blown away by the bulbs. The bulbs were the Arcadia T5 Tropical Pro for plant growth and the Arcadia T5 D3+ 12% UV tube. I have since also used this combination with the Arcadia D3 6% T5 UV tube.”

Product Safety

Lamps can be fragile pieces of equipment. Please follow the following steps to ensure the safe fitting and use of fluorescent lamps.

At either end of a fluorescent lamp you will see two brass coloured connection pins. These are the electrodes that take energy from the controller to start and run the lamp. These are quite fragile by nature. It is imperative that both pins are safely located into the pin sockets inside the lamp holder before the lamp is pressed into place. Failure to line the pins up correctly will cause the pins to bend and snap and break through the lamp cap rendering the lamp unusable.
The Ultra-seal lamp ring must be unscrewed from the lamp holder and placed over the lamp prior to fitting and only re-seated onto the lamp holder when you are sure that the lamp pins are seated correctly. High Output T5 lamp leads must be fully unwound also or you may notice lamp flickering or beaks in illumination. You can also use a very small amount of a substance like Vaseline to lubricate the lamp ring and so stop it fusing to the lamp after long periods of heat. After cooling lamps can be wiped clean with a damp cloth once every two weeks or so to remove any dust build up from the lamp, this in turn will help to maintain the lamps full output. The all important reflector should also be wiped clean at the same time.

D3+ 12% UVB HO-T5 lamps are very powerful lamps. For the first time ever we can now use this tech to generate a targeted wild UVI for our animals. It is important however that arboreal animals are not able to bask for long periods with a reflected D3+ 12% lamp that is fitted closer than 12” from the lamp to the animal as the UV Index would be higher than is required. Fit these lamps as part of a well thought out photogradient and as part of the light and shade method. This then allows great self regulation in a safe environment.
