I have a corn lamp, it didn't last long. LEDs keep failing. keep having to replace individual ones.

Average Life: 45,000 Hours

After having quite a few LED bulbs fail in fairly light use after
about a year, I treat these sorts of claims with a pinch of salt.

Most LEDs are rated at 100,000 hours on their own, and 50,000 hours inside a fitting. But most companies put them far too close together and they overheat. The only LED lights I've seen last for ages are ones that look like fluorescent tubes. The LEDs are well spaced out and never exceed body temperature.

A decent 70w HMI has an output of about 5600 lumens.

Your LED claims 1700. Which is almost certainly optimistic.

That lamp is way less light output than a 70W metal halide - probably
only around 1/3rd.
Secondly, because the light source is not going to be in the position
the luminare was designed for, it's likely the luminare optics are not
going to direct as much light in the right direction.
Thirdly, being a much bigger light source, it's likely to block much
more of the reflected light from the rear than would be the case for
a metal halide lamp, further reducing output.

I suspect you will be disappointed.

You will need something in the 50-60W power rating, and with light
output directed (because the reflector isn't going to be very
effective with a large opaque bulb fitted. Something more like:

http://www.eslightbulbs.com/wp-conte...gh-Power-1.jpg
(which is 60W, and roughly same output as a 70W halide lamp).

TBH, I'm not sure it's worth changing the lamp to LED. If you really
want to go LED, it would be better to change the luminare for an LED
one, but you aren't likely to make any savings to pay for that if you
are already using metal halide.

Its not going to be anywhere near as bright as the metal halide lamp.

How well ventilated is the fitting as a LED lamp doesn't like being much
above warm.

Sorry for delay, been offline. It's actually for a thorn street lamp
in a small yard which has burned out it's igniter board and blown the
bulb.

Just looking to simplify the repair, I can live with lower output but
need a long life because of LOLER requirements when changing lamp.

Large LEDs do generate heat in their PS. You'd need to be sure the fitting
allows the LED to run no hotter than it is designed to. But in my
experience, many of the claims for LED life have to be taken with a pinch
of salt - especially on a rareish type like this.

Notice you have to register it to get the 'free' 5 year warranty. Be
interesting to see the conditions of this.

Take the top off the pole and fit a LED flood light?
A good 30W one should be OK.
If its a concrete pole you probably want to make a bracket and fix it
with stainless banding.

You might want to consider a dual arc lamp, such as GE Superlife.
One arc runs, until it dies, and then the other arc runs. It will
cost more, but your relamping cost is probably much more than the
parts.

Note, you don't want a dual arc grow lamp (that's something
completely different - both arcs run together for different colours).

Well as your LED option is not a guarantee a longer life in this case
then I would be looking at swapping the ballast and lamp or follow
dennis suggestion of strapping a LED flood light below the existing head
(swapping the head for a proper LED head sounds expensive).

When it's expensive to get up there, use a hoisted light fitting. Or you could fit a bunch of lights, and switch from one to another on the ground as they fail.

You need to be trained and competent under Health & Safety at work
act, no need for the course, that's just proof to cover your employer.
I have a apposite qualification (City and Guilds NPTC Level 3 Award in
the Safe Use of a Chainsaw from a Mobile Elevated Work Platform (QCF))
but it still costs a couple of hundred quid to hire a mewp and get it
to site and back.

In newer theatres (and I think TV studios) the whole lighting 'grid' can be lowered. In older theatres in many cases it's possible to walk on the ceiling grid.

In other cases a tallescope is often used - carefully.

On Wednesday 24 June 2015 Stafford Borough Council was fined £20,000 after an incident on 16 July 2014 where Stafford Gatehouse Theatre employees were using a Tallescope which overturned causing the worker in the cage to suffer a fractured bone in his back. There were only two workers involved and the Tallescope was being moved with a person in the cage.

Don't really see why you'd need to lower the entire grid.

TV studios tend to have lighting barrels which can take several lights or
telescopes which take a single one. Both usually with some form of
electric motor to raise and lower them. Individual lights may need to be
at different heights, so moving the entire grid not needed.

As regards house lights, many are also on a winch so they can be lowered
for servicing. Or accessible from within the ceiling.

Why?
It looks stable to me.
They could have replaced the beam out of the window with some rope to
scare you some more but it would still work.

It doesn't look too different from what Fred Dibnah would have
sometimes done in some situations , and to some that he worked liked
that made him an a folk hero . Anyone else doing similar becomes a
reckless idiot.
