## Description

Apollo Horticulture is pleased to present a new wave of efficiency and stability to their line of Grow Lights by introducing the new T5 Grow Light System. Our T5 System is designed to compete with high intensity discharge bulbs in terms of light intensity and output. This grow light is formulated to offer you the following benefits:Efficiency: T5 Bulbs are small in diameter, but work as bright and efficient light sources. The average useable life span for these bulbs is well over 20,000 hours.Dependability: Man-made light sources experience some level of lumen depreciation over time. T5 Fluorescent bulbs will only depreciate between 8 and 10 percent of their rated lumen output throughout their lives.Cost-Effectiveness: Less wattage = lower cost. A key factor in switching to T5 lighting is its ability to not only produce better light, but also to do so while consuming far less energy.Superior Plant Health: T5 lamps promote incredible health and bloom of seedlings, cuttings, and produce enough light for full-term growth.

## Questions & Answers

**Q: I have a Standard 3-Tier Sunlite® Garden that uses T5 bulbs.  Do you know if these bulbs will work in it?**
A: What I have found out the hard way with T5 bulbs, is that you need to get the correct wattage for the fixture.  I put in some low watt bulbs in my 4 bulb T5 fixture and noticed that the bulbs developed black rings near each end of the bulb, and burnt out quickly.  This was because the ballast put out more energy than the cathodes were meant to handle.  Check what is stated on your ballast for the correct bulb wattage.

**Q: Is there an output spectrum graph available?**
A: i have not found one but it is 6000K so it does the job for me

**Q: Is 4,850 lumen the total output or the output for a single bulb?**
A: Each bulb is 4850 lumens.

**Q: Do these bulbs fit the Hydrafarm Fast Start 4' system?**
A: i AM NOT sure because mine Hydrafarm is not a 4' system.  I have the 4' bulbs but had to buy a special fixture for these bulbs and this special fixture is not cheap.  When I purchased these bulbs I thought that they would fit in the smaller bulb shop lite fixture but they are much smaller.  They are the size of your under counter lights used in the kitchen only they are 4' long.

    Fantastic product & price!!!
  

*by J***E on Reviewed in the United States on February 20, 2016*

We were so excited to find these bulbs!!!  I have a "Jump Start" system for my house plants.  I had looked everywhere for these grow light bulbs.  The only thing I found was the bulb with the light reflector system. The company wanted $49.95. Ridiculous.  PLUS, the price is for 5 bulbs!!!!  Was packaged beautifully.  Nothing broken!!!  Highly recommended!

    I had just saw our mailman drop the box over the 5' high
  

*by G***Y on Reviewed in the United States on August 1, 2014*

Packaging is very good for these quality Grow lights that work great. It was like a scene from a comedy movie with the delivery guy kicking and dropping the package. I had just saw our mailman drop the box over the 5' high gate and thought those bulbs got to be bad now. Every single bulb worked perfectly and as described and will buy them again.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Nice Lighting
  

*by M***Z on Reviewed in the United States on October 27, 2014*

The bulbs changed the color in my office to a more natural color. It took a few days to get used to. My co-workers remarked how they never noticed how yellow the other lights were until they see the contrast between my office and the others. Even the colors in my office seem different, more natural.
