So please be advised. For instance: “Shop Lights” for Most new “shop lights” from Home Depot, Lowes etc. can only run 32-watt 4 foot tubes. And not these 36w tubes.

However, most BETTER-QUALITY fluorescent light fixtures with electronic ballasts can run both 32w and 36w tubes.

So, BEFORE BUYING these 4 foot bulbs, please remember to check your 4 foot fixture to make sure it is one that can run these 36 watt flo. tubes properly.

The other option is to save money in the long run and switch to new High Out Put T5 fixtures and bulbs.

HO T5 Fixtures and bulbs are WAY BETTER than these old t8 bulbs and the 1940’s technology used in them.

With new High Out-put HO t5, you save money on electricity and they pay for themselves.

Not to mention you get easily about 50 – 60% MORE UVB & light using HO t5 over these T8 bulbs. Thank you.

Europe's TOP OF THE LINE Reptile 6.0 bulb is NOW AVAILABLE in North America! Imported direct from the UK by LightYourReptiles.com. NOTE: These lamps are designed for Vitamin D synthesis AND the tetrachromatic visual needs of your Reptiles and Amphibians. Forest species such as the Day Gecko, require lower levels of UVB and should be kept under an appropriate sized 6% UV-B D3 lamp, which contains ample levels of UV-B radiation for such species. • 6% UVB for the synthesis of vitamin D3 • Full spectrum lamp • Produces excellent natural colours The Arcadia D3 Reptile lamp has a high UVA output (30%), providing all the elements which are so vital to the welfare of the reptiles. As a full spectrum lamp, the Arcadia D3 Reptile lamp simulates sunlight. This provides high colour rendering for enhanced viewing of your reptiles and their environment. The colour temperature of 6,500K replicates typical daylight conditions. The D3 lamp also helps plants grow in the vivarium or terrarium, where these are present. Arcadia reptile lamps are specially formulated to produce light in the UVB and UVA wavebands, as well as visible light and use a special glass formulation designed to allow through far more of the UVB and UVA. This means that we can offer lamps with spectral radiation patterns tailored to meet the requirements of specific reptile species. It is important to note that sufficient vitamin D3 is not enough in itself to avoid metabolic bone disease. Reptiles should also be fed foods rich in calcium and phosphorous. Do not use a glass or protective lens between the lamp and the reptile – this will reduce the UV light that your reptiles need. Fix the lamp at the top of the vivarium. The addition of an Arcadia Reflector will ensure that all the light is focused downwards and the intensity is increased. For nocturnal species, make sure that there is an area where they can shelter away from the light and give them the necessary period of darkness each day. Both UVA and UVB can damage the human eye in sufficient quantities. The D3+ and D3 Arcadia lamps are designed to have no more UVA or UVB light than is found in natural reptile habitats. This does mean however that you should restrict your exposure to this light, just as you would avoid looking at the sun. The amount of UV produced by reptile lamps lamp falls the further away the lamp is. We recommend that the lamp should be kept within 12” or 30cms from your reptiles. It is important that reptile lamps is replaced at least once a year. The human eye cannot see the reduction in UV output over the life of the lamp, but this phenomenon occurs with all fluorescent lamps. UVB Light Most reptiles need to synthesize vitamin D3 in their skin for their healthy growth for which UV light falling within a particular wave band, known as UVB (290-320 nm), is required. Although Vitamin D3 can be commercially obtained from animal sources, and given to reptiles with their food, studies have indicated that dietary D3 cannot replace the D3 synthesized in the skin from sunlight, even in reptiles injected with supplemental vitamin D3. The vitamin D type derived from plants is vitamin D2 and is not suitable for proper calcium metabolism. For the best results, vitamin D3 must be obtained from regular exposure to UVB light, either from natural sunlight or specialist reptile lamps. The Arcadia reptile lamp range has been created in order to allow reptiles and other exotic pets to be maintained without the health problems related to poor calcium metabolism. UVA Unlike humans, who have ‘trichromatic’ vision, enabling us to see only three primary colours - red, green and blue, we now know that many reptiles, amphibians and other species, have ‘tetrachromatic’ vision. This enables them to see the shorter UVA wavelengths (320-400 nm) of the spectrum that form a part of natural sunlight. Reds are redder and greens are greener – life without UV would be the equivalent of us seeing everything in black and white, only worse. This UVA, or fourth primary, can be critical for behaviour and even affect appetite. A reluctant feeder may need UVA light to stimulate its appetite. UVA is also needed to induce reproductive behaviour. Lizards have been found to possess ultra violet reflectance patterns on their skin, which indicate reproductive glands in particular. Female panther chameleons seek out UV light when preparing to lay eggs. Depriving a reptile of UVA light would be like making it live in a darkened room.
