Sorry my reponse took so long but I broke my phone anyways 175 watt metal halide is what this ballast is set up for beware purchasing make sure it comes with the bulb and for added safety u should purchase the protective lens from them also to make it safe or else one drop of water can rupture the bulb

It uses a small bulb like a appliance bulb. Can't measure it cause it is in storage.

you will measure the bulb length, not the fixture length. So you would continue with an 18 inch bulb.

It's a European size....dumb. There was a review submitted that said he found a bulb that worked for it that you could get in US.

Hello Cathy, Thank you for asking! Typically, in an 8" pot we recommend 6 bulbs, you can certainly go smaller if you wish. So, in a 4" i would put 3 or 4. http://www.easytogrowbulbs.com/g-18-oxalis-planting-guide-regnelli-triangularis-others-from-bulbs.aspx Copy this link to see our growing guide as well. They are super easy and take almost no water to get started! Let me know if I can assist further. Best Wishes,Dena GrangeEasy to Grow Bulbs

All I really know about mine is it uses 2 -7 watt small blue light bulbs also has temp control I love this brooder system and have bought more grow pens with the extensions and love them. It has paid for itself.

This 20 inch fixture works great on my 16 gallon bow. I also use 2 of them on my 60 gallon cube, and I am buying one right now for my 26 gallon hex. I use a 15W 18 inch Life Glo T8 bulb, which is by far the best bulb I have found to grow plants. The plant plus LED on my hex doesn't grow the plants, only algae. I also have a 24 inch Life Glo bulb on my 35 gallon bow that grows plants like crazy--I use the trimmings as new starts. I like to trim them down 6 inches below the top, then when the stems split and grow up, you have multi-stem starts instead of single stems as sold in the LFS.

Pretty hard for me to measure because it is intalled up high in my ceiling but it was a drop-in replacement for a GE EXN 50W 12 Volt bulb. I noted no size difference when I did the job. Hope this helps.

I have used several different bulbs. A regular 60 watt bulb fits fine. An energy saver bulb fits also.

It has a pigtail about 4' long with a standard plug on the end. I put grow bulbs in it and use it for over seed trays. I like having the switch for individual controls.

Depends on the diameter of the can. The diameter of the bulb in 3-3/4 inches.

No sir. It will blow the bulb. The smallest bulb you can use is a 400watt. The ballast is dimmable. It does 100%, 75%, and 50% power. 50% of 600 is 300. I have used a 400watt with it and it did fine. Good luck, great grows.

Sorry for my delay. I don't remember...I believe it was in the instructions. We used a 25 watt bulb.

The light will fit a 10 gallon tank hood I believe. Make sure you get a good bulb to promote plant growth.
