Squash Court Light Replacement

11/01/2011 6:17 PM

I have considerable difficulty replacing blown lights on the ceiling of our courts. In fact, I have to erect a skaffold each time I need to do so. Can anyone advise if there's a commercially available platform that I can wheel in and out of the courts to complete this task; bearing in mind that I only have a standard height and width door to gain access.

Have you considered an electric scissor lift? You could also try a fiberglass pole. Depending on your agility you could go with stilts or even jumping shoes.

Why don't you rig the lights to come down to you?

You could use a mechanism like they use for basketball backboards, only much lighter. You'd have to put the electrical feeds on a retractable reel.

You need a Genie Lift (or thats what they are called here) easily pass through a double door and run from a standard single phase power outlet.They travel and operate all from the cage lift is fine for most auditoriums.

There are also telescoping manlifts (sort of like a forklift mast) that can pass through standard 30" x 80" doors. Grainger Industrial Supply [no personal connection] is one source. They don't generally motor around like a scissors lift; rather, you put them directly below the work and go straight up.

There was a company here in Calif. that made a scissor lift that fit through a standard 30"x 80" and extend 20'which would give you somewhere around 25-26' total height, all electric and self propelled. I think they move their factory to Ireland, the company was called UpRight Inc. I still see some of their equipment around here in Calif. Don't know if that was any to you

As many have pointed out here, a man lift is the easiest way to go and it can be used for many other overhead projects.

I bought one used to re-finish the interior and exterior of my home.

Will fit through most walk through doors, easy to roll on a hard surface, not so easy to load into a pick up truck bed though.

Very stable work platform.

Mine is a 24' which gives me a 30" working height.

Just curious.

I notice you have log siding and what appears to be a corn field across the road. The stereotype suggests you live in the country and possibly hunt. Does the lift double as a tree stand? I have been looking for a battery version for the same purpose.

We don't know how high your ceiling is, so that would help immensely in regard to answering your question.

Have you ever though or tried to use a telescoping light-weight light bulb changer? I have one here that's made of aluminum and can reach 30-foot high ceilings.

Also, look in to USA-made CREE LED 120 VAC lamps. I just bought a whole bunch of them for the new track lights in our kitchen and living room (has very high ceilings).......120 VAC, 8W (replaces a 75W Halogen bulb), daylight white, 650 lumens, dimmable, standard Edison E26 screw-on, and 60-degree flood. The design life is 40,000 hours.....equivalent to running them 24/7/365 full power for 4.57 years! OR at 8 hours per night time running that's 13.7 years lifetime. Sure they cost me around $31 per bulb, but it eliminates all the hassle of changing them every few months or the ever ending replacement costs of installing new bulbs! Even with a 60-degree flood cone they're extremely bright!!!

Mrs. Moosie loves them in her refurbished kitchen!!!

Hey Capt.Moosie, I see that you have your LEDs on a dimming circuit, I was wondering how that's working out for you? I'm curious if they have any draw backs, like not dimming below 30%, like the draw backs of CFLs?

I also have some LEDs on a dimming circuit. They don't go as dim as far as I expected but there's a more startling but pleasant effect I've found. Dimming a daylight color spectrum LED is like adding a neutral density filter to the lamp. The lamps do not go yellow when dimmed.

Thanks CaptMoosie and redfred, this just gave me another option for a place that I was just asked, today in fact, if I could come in and straighten out their electrical problems. One problem is that they wanted to run 3 different sets of track lights on dimmer circuits using CFLs. Anyhow, I'll run it by them tomorrow and talk them into the LEDs. As it is, someone really screwed up running the electrical circuits and then covered up the mess with sheet rock. I pissed them off when I told them that about 80% the sheet rock has to come back off to fix it. Now, if I can just keep the Inspector away long enough so I clean things up, I'll be a Happy Camper.

Re: Squash Court Light Replacement

11/02/2011 1:37 PM

Hiya, well for starters I have 10 of the LEDs on the single kitchen circuit, or 4 more than the required minimum amount, to prevent flickering. To tell you the truth I'm sick and tired of replacing CFLs around here as they just don't hold up for very long. I suspect that we have line surges. I suppose I should install a entire house surge protector. The important electronic toys here already have their own dedicated ones...

Secondly, I'm using a Lutron Duo Maestro MAW-600H digital fade dimmer (it's a slide type and one of the recommended dimmers). I can get the lights to fade down to approximately 10% (that's the spec.), with no problems whatsoever so far....I've only had them in less than a week.

Here's the LED bulb info:

PAR30 R30 BR30 LED CREE EQUI 650LM G70 DIMMABLE E27

Note: I bought them on Ebay for a very good price!

I have seen poeple changing globes with a telescopic pole that holds the globe.

If your light is not set up for this it could pay to get it modified for future savings!

If the light volume and quality is acceptable for you (try it out), the power LED is definitely economical for you. But, for the present check out the voltage feeding the present lamps. Any slight overvoltage burns out bulbs quick. Slight undevoltage extends their life manyfold. The power company can adiust the voltage to the building.

The question now has to be, screw-in, or tube lights?

Just get a really good pogo stick, but you'll have to work very fast when you get up there.

Again depending upon the height you need, consider this: http://www.liftpod.com/en-US/Home.html. It is a sort of mini-manlift that uses a battery-powered electric drill for the drive (or a hand-crank), and will go pretty much anywhere. Watch the video.

Change out the lights. Use induction lights. They are similar to fluorescent in appearance, color of light, and brightness, but the fixtures and bulbs last for 100,000 hours before changing anything. That equals 23 years if the lights are on 12 hours per day, every day. Your local lighting factory representative can get you information on the lights. Philips and Neptun are well known manufacturers of this type light.

I wonder if the lights are on a sensor, as I have passed many courts where people leave the lights on after they leave. Prevention is better than cure. Also look in to http://www.eyelighting.com/ as I remember when I worked in the lighting industry that they were one of the most efficient in situation like this, a little more expensive per bulb but consider the cost of replacement (maintenance and downtime)

It is evident that a few responders have never been in a squash court. Almost identical to a racketball court. Probably has recessed lights in the ceiling (20' tall). The access door for many a court is not a standard opening (some ~24"x5'). Really need a work platform of some sort.

Not much help, just trying to help clear things

You're correct that many here have never been in a squash court, but the OP states that he has a standard door. He doesn't explain which standard door width enters the squash court but it is some standard. If we're going to dispute the little bit of information we do get from an OP, we will never be able to answer their questions. For all we know, our OP may just not realize that the locked service door on the next floor up from the squash court provides easy access to the court lighting.

True - it's a fair bet that at least some of us have never SEEN a squash court, nor a racquetball court (my hand is up at this point, to indicate that I'm one of them) - but we DID ask about the height and for clarification on the type of lights. The initial post specifies that the court has a standard door, so we didn't ask about that (though someone did mention a device that requires a double door for access). It appears that our thread originator has not returned to check whether the question was answered - at which point most of us are probably saying to ourselves, "What? Someone posted a question and then didn't return? AGAIN? Ho-hum..."

I have one of those. The wife through a hissy fit over the price until her mom and nephew ooohhhed and aaaahhhhed over it. Then it was OK. As an A-frame ladder it is great. The narrow treads are a bit hard on the arches. That's why they sell the "work platform" to stand on. We are building a shelter house and I tried to use it as an extension ladder inside the building. Very awkward to do so by yourself if you have to extend it while it is already vertical. All in all a great product.

Good morning,

Despite what at least one member has stated - I have been reviewing responses to this thread since inception and I thank everyone for their comments. I believe that I now have enough information to proceed on my quest in a positive fashion.

Thanks once again to all who have made positive suggestions.

I apologize for my comment - but at the same time, note that we did NOT receive clarification as to height, nor type of lighting, as was requested. And now, it appears that you have chosen a course of action, but offered us no feedback so that we can see what helped, and what didn't. One of the reasons for being on this site is that we are able to learn from each other; feedback is a quite significant part of that process, IMHO. Can you at least tell us what you intend to do? Thanks in advance.

Re: Squash Court Light Replacement

Good evening All,

I do apologise for not sharing my proposed solution. Given that the lights are up to 6m above the playing surface and are Metal Hallide-type, I need something that will allow me to reach the lamps when cold in a safe and steady manner. Essentially, I plan on pursuing the following product: a Snorkel PAM 21 / 26 Personal Lift, as the specifications stated seem to ideally match my requirements (with a maximum platform height of 8m) and a footprint (when stowed) of 0.69m x 1.2m (height of 1.98m) that should enable entry via the door provided.
