LED High Bay 100 W: 200 lm/W, 20,000 lumens, Philips driver
A UFO high bay for warehouses, workshops, production and logistics that does three things
differently from the usual stock: 200 lumens per watt instead of the common 120 to 150, a
90-degree beam instead of 120 degrees, which sends less light into shallow viewing angles,
and an output you switch between 70 and 100 watts on the housing.

200 lm/W is the reason this article exists
Across 100-watt high bays the usual figures sit between 120 and 150 lumens per watt. This
luminaire reaches 200 lm/W, in all three colour temperatures.
The gap looks small as long as you only compare wattages. It becomes obvious once you fix
the amount of light and put the electricity bill next to it.
The calculator further down works out what that means for your building. Enter your
existing installation, your operating hours and your electricity price.

A worked example: 20 luminaires
Say you need 20 light points at 20,000 lumens each, running 10 hours a day, 5 days a week,
50 weeks a year. All three luminaires deliver the same light. They just draw it from the
grid with different efficiency.

Based on 2,500 operating hours a year and 17.2 cents per kWh excluding VAT, the German
average for small and medium industrial users (BDEW 2026). If you pay more for electricity
the gap widens accordingly. No electricity price increase assumed.
Energy efficiency class A
The luminaire carries class A under EU Regulation 2019/2015, at 100 kWh per 1,000
operating hours. On the scale that came into force in September 2021, A is the top of
seven grades and starts only at a total mains efficacy of 210 lm/W. Luminaires at the
common 120 to 150 lumens per watt sit two to four grades below that.
The class and the 200 lm/W are the same fact in two languages. The regulation derives the
class from the efficacy.
Each colour temperature has its own label with its own EPREL registration. Class and
consumption are identical across all three.
70 or 100 watts, switched on the housing
A slide switch on the back has positions LOW and MID. LOW gives 70 watts, MID gives 100
watts. You set it on the housing, with no dimmer, no control cable and no change to the
installation.
That helps when a building has zones with different uses, when a side area needs less
light than the assembly bay, or when the use changes later. You order one article and fix
the output during installation.
The third switch position, HIGH, is not used on this model. It is intended for 130
watts, but the Philips driver fitted here tops out at 120 watts. In practice you have
two steps: 70 and 100 watts.
The output switch on the left, mains lead and control cable beside it. The eyelet takes
the hook; the safety wire is supplied.
90° instead of 120°: less glare from shallow angles
Most UFO high bays have a 120-degree beam. This one comes with 90 degrees as standard. The
difference sounds technical, but you see it on the floor.
At 120 degrees a substantial share of the light goes out sideways at a shallow angle. Anyone
walking through the building or sitting on a forklift has the luminaires in their field of
view at exactly the angle where a bright source glares most. At 90 degrees that shallow share
is much smaller. The light lands on the working and traffic areas instead of in the eye.
You notice it most in long buildings with clear sight lines, in racking aisles and wherever
forklifts run. There is a second effect: light that does not escape sideways ends up on the
floor, so the same number of luminaires puts more light where you need it.
For a rough estimate of the light cone at 90 degrees, its diameter is roughly twice the
mounting height above the lit surface, so about 16 metres at 8 metres, with illuminance
falling off towards the edge. Luminaire spacing of 1 to 1.5 times the mounting height is the
usual starting point. We also supply 60 or 120 degrees on request.
Beam angle alone does not make a building glare-free. Mounting height, luminaire position,
room geometry, reflectance and the direction people look all contribute. We do not quote a
UGR figure for this luminaire. If glare limitation is specified for your site, for example
at screen-based workstations, let us go through it before you order.
Philips Xitanium driver
A Philips Xitanium is fitted. The driver is potted to IP65 and sits in its own housing on
the back, so it can be unscrewed and replaced if it ever fails.
In an LED high bay the driver is the component most likely to fail. The LEDs themselves
usually last considerably longer. That is why this page names the driver instead of
saying “premium branded control gear”.

What the changeover saves in your building
Enter what is installed today, how long the lights run and what you pay for electricity. The
calculator shows consumption, savings, CO₂ and the payback over eight years. It takes the
output of this luminaire and the price including volume breaks from this page.
The result is an estimate based on your entries and is no substitute for a lighting design.
How many luminaires you need also depends on ceiling height, building width, racking layout
and the illuminance you have to achieve.
Construction
The aluminium heat sink carries radial fins that take heat upwards.
From the side you see the flat 110 mm body and the separate driver enclosure.
Suspension eyelet, safety wire and carabiner are supplied with every luminaire.
The housing is aluminium, the light emitting surface polycarbonate. The luminaire is rated
IP65 against dust and jets of water and IK09 against impact, which corresponds to 10 joules.
It works between −20 and +50 °C ambient.
The mains lead is pre-fitted in brown, blue and green-yellow. The control cable for dimming
runs separately in pink and violet. The luminaire is protection class I and must be earthed.
Dimming with 0–10 V
The luminaire is 0–10 V dimmable as supplied. The Philips driver is a 1–10 V type, which in
practice means you dim steplessly down to about 10 per cent and switch off through the mains
rather than the control signal.
The combination worth considering is occupancy detection with a dimmed base level: unused
areas run at around 20 per cent and go to full output on movement. That saves on top of the
LED changeover itself, without anyone touching a switch.
If you need DALI, it is a different luminaire
A DALI version exists, and it is not this article with another interface. It is a different
product: a SOSEN driver instead of the Philips Xitanium, 150 instead of 200 lumens per watt,
so around 15,000 instead of 20,000 lumens at 100 watts, and 4000 K only.
If DALI is fixed in your building management system we will of course supply it. Check first
whether 0–10 V is enough: for daylight or occupancy dimming this luminaire does the job and
gives you a quarter more light for the same power draw. Talk to us and we will compare both
options for your project.
Colour temperatures
We supply 4000, 5000 and 6000 kelvin, each at 20,000 lumens and 200 lm/W. 4000 K neutral white
is the usual choice for storage, workshops, production and logistics. 6000 K gives a
noticeably cooler picture for technical areas.
5000 K: less often stocked, often the better choice
The trade is dominated by 4000 and 6000 K. 5000 K sits between them and is stocked less
often, although it is the better choice in two situations.
The first is daylight. As soon as roof lights, window bands or an open door come into play,
two colour temperatures meet. Daylight usually sits between 5,000 and 7,000 kelvin, and next
to 4000 K luminaires it looks distinctly blue while the artificial zones look yellow. The
transition is visible, particularly near the door. At 5000 K the break is far smaller.
The second is fine visual work. Edges, scratches, burrs and surface defects generally stand
out more sharply under cooler light. For inspection, final checks and assembly of small parts
5000 K is often the better choice than 4000 K, without the picture becoming as harsh as at
6000 K.
One limitation belongs here: colour judgement depends on colour rendering, not colour
temperature. This luminaire reaches CRI 80, which is fine for storage, workshops and
assembly. For colour matching, paint inspection or print approval you need CRI 90 or above,
and this luminaire is not intended for that, not even at 5000 K.
3000 K warm white: available, but as a different model
We supply warm white in the 150 lm/W version of the same series, in the same housing, with a
Philips driver and 0–10 V dimming. It is not this article, and the difference is substantial:
14,000 instead of 20,000 lumens at 100 watts, 140 instead of 200 lm/W, energy class D instead
of A, and a 120-degree beam as standard instead of 90 degrees.
Warm white is the exception in an industrial building, but it has its cases. Event catering
and function spaces are among them: converted industrial halls, market halls, venues for
parties and trade shows, where the light should feel warm and welcoming rather than look like
a warehouse, and the ceiling height still calls for a high bay. The same applies to retail and
showroom space and to hospitality in older buildings. Talk to us if you need 3000 K.
Where it fits
- Warehouses with racking, traffic routes and general storage areas
- Workshops, work areas and assembly stations
- Manufacturing and assembly areas in production
- Logistics, dispatch and order picking
- Retail and showroom space with high ceilings
- Agricultural buildings and machinery sheds
For sports halls the luminaire is only suitable after assessment. Ball impact resistance to
DIN 18032-3 is not certified for this article, and glare limitation needs its own design there.
Accessories
Polycarbonate reflector
The reflector is fitted under the housing and encloses the whole light emitting surface. It is
made of clear, finely ribbed polycarbonate. The ribs scatter the light rather than simply
letting it through, so instead of one bright spot you see an evenly glowing surface.
That does two things. The luminance spreads over a larger area, so the luminaire looks far
less harsh in the field of view, and the reflector pulls the distribution further downwards
on top of the already narrow 90-degree beam.
Worth having wherever the luminaires sit in people's line of sight: lower ceilings, areas
with screen-based work, or buildings customers walk into. The cost is light. Any scattering
loses output on the floor, so allow for a few more luminaires with the reflector fitted.

through in a beam.
Mounting bracket
The bracket replaces suspension from a hook or chain and allows fixed, aimed mounting, for
example on a wall, a beam or under a canopy.

Frequently asked
How many watts is 20,000 lumens?
It depends on how efficient the luminaire is. This one needs 100 watts, because it
reaches 200 lumens per watt. A luminaire at 150 lm/W needs around 133 watts, one at
120 lm/W around 167 watts, one at 100 lm/W exactly 200 watts. Divide lumens by lumens
per watt.
How many lumens do I need per square metre?
EN 12464-1 does not specify lumens. It specifies illuminance in lux on the working
plane. Typical figures are 200 lx for storage areas with people continuously present,
300 lx for order picking and rough assembly, and 500 lx for fine assembly and quality
control.
As a rough first estimate, designers work with 150 to 200 lumens per square metre for
warehouses and 300 to 500 for industrial buildings. That is a rule of thumb, not a
calculation: ceiling height, wall reflectance, dirt and racking layout all change the
result considerably.
How many luminaires do I need?
The rough sum is floor area in square metres times the target lux, divided by the output
of one luminaire, then rounded up generously. For 1,000 m² at 200 lx with 20,000 lumens
per luminaire that gives 10 on paper and more like 13 to 15 in practice, once you allow
for utilisation, dirt and lumen depreciation.
Space them evenly on a grid, at 1 to 1.5 times the mounting height. Send us a floor plan
with dimensions, ceiling height and intended use and we will tell you the number and the
layout.
Can it replace metal halide or mercury vapour?
In most cases yes. A 400-watt metal halide or mercury lamp draws around 450 watts with
its ballast and gives roughly 22,000 lumens when new. After a few thousand operating
hours only 70 to 80 per cent of that is usually left.
At 20,000 lumens from 100 watts this luminaire normally replaces such an installation
one for one and saves around 350 watts per light point. Check the suspension, the light
distribution and the existing wiring before you swap. The calculator on this page works
it out for your quantity.
Does it glare less than a 120-degree luminaire?
At shallow angles, yes. A 120-degree luminaire sends a substantial share of its light
sideways, and that shallow share is what lands in your field of view when you walk or
drive a forklift. At 90 degrees less light goes that way and more goes onto the floor.
That is an improvement, not a guarantee. How much anyone is glared also depends on
mounting height, luminaire position, room geometry and reflectance. We do not quote a
UGR figure. Where glare limitation is specified, please go through it with us first.
How do I set 70 or 100 watts?
There is a small slide switch on the back of the driver enclosure with positions LOW,
MID and HIGH. LOW gives 70 watts, MID gives 100 watts. Set it before installation, with
the supply isolated. HIGH is not used on this model, because the Philips driver tops out
at 120 watts.
How do I wire it to a dimmer or occupancy sensor?
Mains goes to brown (L), blue (N) and green-yellow (earth). Dimming runs on the second
cable: violet is 1–10 V positive, pink is 1–10 V negative. Those two cores go to the
control output of the dimmer or sensor, kept separate from the mains.
If you are not dimming, leave violet and pink insulated and unconnected; the luminaire
then runs at full output. For larger groups fit a contactor for the mains, because the
inrush current of several drivers will overload a simple switch. Installation is work
for a qualified electrician.
Is it suitable for outdoor use?
IP65 means dust tight and protected against water jets from any direction, so it can be
used under a canopy, in a wash bay or a drive-through building. A UFO luminaire of this
shape is not intended for fully exposed mounting without cover, not least because water
collects on the horizontal cooling surface.
Not sure about quantity, output or colour temperature?
Send us a floor plan with dimensions, the ceiling height and a short description of how the
space is used. We will tell you how many luminaires you need and where they should hang.
