This instructable will show you how to convert a metal halide architectural light, commonly used to illuminate gymnasiums, outdoor stairwells and parking structures, over to a more energy efficient and longer lasting induction lighting setup.

While yours may differ, I am demonstrating on a RAB brand metal halide lamp, converting it over to Philips brand induction components.

I will also take a moment to mention that you will be working with electricity and this work should be only attempted by a trained professional. Always when working with electricity practice basic safety precautions and before you preform your work, make sure the power is switched off at the circuit breaker.

Step 1: Remove outer lens

Remove the four screws holding the outer lens.
Remove the outer lens.
I like this instructable. Here in Des Moines, Iowa the local Northern Tool Supply remodeled their store. One of the improvements was the installation of the induction lamps. The store is definately brighter! I asked one of the employees what kind of lamps those were but he didn't know. It looks like a VERY large flourescent lamp. I have a work shop 30'x50' with 20' rafters, THIS is the light I am going to install and I also have a mercury lot lamp I am going to retrofit also. <br> I did a search on YouTube and found a number of vids showing fixture modifications from MHD. This first vid shows the induction lamp like the one in this Instructable; the second vid answers alot of questions i.e.; how bright is it, how long will it last, how much less power does it use? <br> <br> I have attached a links for all to view. I hope this helps. <br> <br>http://www.youtube.com/watch?v=lTcdJ6tNXrQ&amp;feature=related <br> <br>http://www.youtube.com/watch?v=9W_jvPjHWrU&amp;feature=related
Hey just for future use, the rectangular box is a ballast not a generator. Generators create electricity, ballasts transform it. Just thought I would let you know so people didn't become confused. Good job otherwise.
Induction Lighting uses radio-waves to produce light, so, the box <em>should</em> be called a RF-generator.<br/>
It is labeled by Philips as a "HF Generator" and is referred to in the installation instructions as a generator.
Have you got a pic showing the induction lamp in place? L
Sure do! I added it to step 7.
Ah right, and the glass bit goes over the top. Yes I see it thanks. L
Isn't the glass bit the lamp, and the metal pole thing where the coil is that lights the lamp?
The pole with the wire wrapped around it is the lamp and is what illuminates. The glass "bulb" is just a cover for the lamp.
Really? How does it illuminate, I thought that pole with the wire emitted the high frequency which excites the gas in the glass bulb.<br/><br/><em>The discharge vessel consists of a hollow soft glass bulb, containing a tubular re-entrant portion at the centre such that the antenna can be inserted into the lamp but is not in contact with the lamp's internal atmosphere. The re-entrant is coated with an electron emissive material, while the inside of the bulb is coated with a triphosphor fluorescent powder and anti-blackening agents. A thin electrically conductive coating on the outer surface serves as a shield to prevent radiation of HF signals outside the bulb. The internal atmosphere is a neon-argon mixture and because of the high operating temperature, special amalgams are necessary. One is attached to the re-entrant, while the other resides in one of the two exhaust tubes in the base.</em><br/><br/>Read more <a rel="nofollow" href="http://www.lamptech.co.uk/Spec%20Sheets/Philips%20QL85.htm">here</a><br/>
