ATI 24 Inch 24W True Actinic 03 T5HO Fluorescent Bulb Information


Product Manuals & Documentation

Produces a violet-blue light that is designed to maximize fluorescence in capable corals and make livestock colors pop.

ATI T5 Bulbs have been at the forefront of T5 bulb technology since there 1st introduction in 2000. Since then, ATI Engineers have continued to research and develop ways to manufacture an even better T5 Bulb.

ATI`s NEW GENERATION of T5 Bulbs continue this tradition of excellence. Unlike other brands, including other German-made T5 bulbs, ATI T5 Bulbs use the latest advances in phosphors (phosphors are the stuff inside the bulbs that emit light) and manufacturing techniques to produce bulbs with higher output, better coloration and more stability. By using better quality phosphors and improved manufacturing techniques, the new versions of the ATI Blue Plus and ATI Aquablue Special have better output and improved color over the previous generations. And as you all know, ATI was proud to release the all new ATI PURPLE PLUS Bulb, which was developed to replace the ATI Pro Color. Lastly, while again keeping the hobbyist in mind, ATI bulbs are also very affordable making them a great value and a preferred choice of experienced hobbyists throughout the world.

Length (including pins): 22 1/8”

Available Colors:

Aquablue Special: Combines the properties of a full-spectrum bulb with an elevated blue color peak producing a bulb with an approximate color temperature of 15000K.

Blue Plus: Combines the properties of a blue bulb (approximately 460nm) with an actinic bulb (approximately 420nm) producing an intense blue light with high PAR numbers and a light spectrum that encourages both bluing in SPS corals and fluorescence in capable corals.

Coral Plus:Combines the properties of a Blue Plus (~50%) + Aquablue Special (~40%) + Purple Plus (~10%) producing a bulb with an approximate color temperature of 15000K+. Appears cool, crisp white to the eye.

Purple Plus: Combines the properties of a full spectrum bulb with strong red and blue components producing a bulb with excellent color-rendition that works very well for bringing out the pinks, purples and reds in an aquarium.

True Actinic: Produces a violet-blue light that is designed to maximize fluorescence in capable corals and make livestock colors pop.

Comments: I switched from LED lights to ATI T5 about 4 months ago and have these bulbs in my ATI fixture. Night and day difference. I bought cheap LED's and also VERY expensive LED's (wont mention name) and nothing compares to the coloration and growth of corals than what these lights put out!

Comments: I can honestly say after 15 years in The hobby, that the ATI T5 bulbs are the best that I have used on my reef tanks. I just won't use anything else since switching to them years ago.I must also mention that Marine Depot is about the best place to get them. The UPS folks smashed up a box and broke a couple bulbs somehow in delivery last time,and Marine Depot replaced them no charge and very quickly.

Comments: I bought four of the 48" ati bulbs for replacement. I really like the color that the combination I have gives off which was suggested by a representative. The package arrived quick and the packaging was unbelievable. Marine Depot made sure the bulbs were well protected. Thank you and will order again from Marine Depot.
