How to Position a Floor Lamp for Sewing Without Casting a Hand Shadow

To position a floor lamp for sewing without casting a hand shadow, stand it beside your left elbow, not behind you and never on the machine side: pole about 50 to 60cm to the left of the needle line and 20 to 80cm back toward your chair, with the open bottom of the shade 45 to 60cm above the needle plate, so the light comes in over your left forearm at about 50 to 70 degrees. From there the only shadow the lamp can cast is your left hand's, and it falls to the left of the needle where there is nothing to read. The needle itself is the machine's own light's job. The floor lamp's job is the 10cm of fabric in front of the foot and the seam guide marks on the plate, and from that one spot it lights both.

This guide is about where the lamp stands when the work is a machine on a table. For a book on your lap, where your own head is the shadow, run the test in our floor reading lamp guide. For whether the lamp fits under your ceiling at all, see the floor lamp sizing guide, and for what an arc lamp's reach figure really measures, the arc reach guide.

Why a floor lamp cannot light the needle

Every domestic sewing machine is the same shape where it matters: a bed you sew on, a pillar rising on the right, and an arm coming back across to a head that hangs directly over the needle. The head's underside is about 5cm above the plate and the arm's underside about 12cm. So the needle sits in a slot, open to the front and the left, roofed by the machine itself. We modelled that slot with a domestic flatbed machine (a 12 by 17cm harp), a table top 73cm off the floor, the plate 8cm above that, both hands resting on the fabric either side of the seam line, your forearms, your chest leaning in and your head 38cm in front of and 38cm above the needle, then traced light from each lamp's shade to the plate.

From a shade 60cm above the plate, light gets to the needle point only at low angles: 10 to 35 degrees above the plate from the left or the wall side, 20 to 45 degrees from the right and front, and exactly 55 degrees from straight in front. Anything steeper lands on the head of the machine. That is why machines carry their own light under the head, pointing at the needle from 10cm away, and why no floor lamp in our range lights the needle point from a sensible place. Across all seven lamps and every legal pole position, the needle was lit from one family of spots only: an Orsay standing 50 to 90cm behind and to the left of the chair, throwing light under the head at a low angle. Useful to know, not something to build a room around.

What a floor lamp can own is everything the machine's little light cannot reach: the fabric arriving at the foot, the seam guide marks engraved to the right of the needle, the 10cm where your fingers steer the edge. We call that the work zone, and we scored every lamp position on five points in it: the seam line 3, 6 and 10cm in front of the foot, and the 1.5cm and 3cm guide marks 4cm in front of the needle. A position is clean when every one of those five is at least 70 percent lit and no bare globe is in your eyes.

The one placement that works: beside your left elbow

Take the Orsay, our open 25cm gold dome with its rim 140cm off the floor and about 52cm of reach from the pole. Stand the pole 60cm left of the needle line and 50cm back toward the chair, turn the arc so the dome points at the machine, and the dome's centre ends up 20cm left of the needle line and 16cm toward you, over the front edge of the table beside your left forearm. All five work points score 100 percent, the light reaches the seam line at about 69 degrees, and the machine head blocks the needle point entirely, as it should. Move the pole anywhere from 50 to 110cm left and 30 to 80cm back and the result stays clean: eleven of the thirteen clean positions for this lamp are in that band, the other five a little further round, 90cm behind the needle and 50 to 90cm to the left.

The short reach lamps tighten the band but keep the rule. The Rousseau (rim 134cm, about 26cm of reach) is clean with the pole 50 to 70cm left and 20 to 70cm back, scoring 100 percent at 50 left and 30 back with the light arriving at about 60 degrees. The Chandelle, a straight linen column with no reach at all, is clean at 50 to 60cm left and 20 to 60cm back, light at about 45 degrees, because its whole 40cm column glows sideways. The Aurelia, our pleated cone on a fixed gooseneck, is clean only along a line 50cm left of the needle, 20 to 50cm back, and that limit is not about shadows. Its rim hangs 127cm off the floor, and a seated adult's head tops out at about 129cm, so every position that would carry the shade over you is out. It stands beside you or nowhere.

The number underneath all of this is where the shade's centre lands, not where the pole is. For an open dome at 140cm, the work zone is clean whenever the shade's centre sits 10 to 60cm to the left of the needle line and 10 to 55cm toward you: over the table's left front edge, your left forearm or the chair's left side. Of the 119 clean shade positions at that height, 103 are on the left; the handful on the right need the shade almost over the seam line itself and still lose the needle. Drop the shade to 134cm and the band shrinks to 50cm each way. Drop it to 127cm and only 27 spots survive, all within 40cm of the needle line and 40cm of you, because 25 further spots would put the rim into your head. The lower the shade, the longer your hand's shadow and the smaller the sweet spot.

Angle explains why the band has edges. In every clean position the light reaches the fabric 6cm in front of the foot at between 45 and 77 degrees above the plate. Below about 45 degrees your left hand, 4.5cm thick and sitting 4cm off the seam line, throws its shadow onto the seam. Above about 75 degrees the light is coming down past the machine head and the head takes the guide marks. A shade 45 to 60cm above the plate, 15 to 35cm to the left, sits in the middle of that window.

The three positions that fail, and why

Where the pole stands	What blocks the light	What you see on the plate
Anywhere on the right, level with the machine or beside your right elbow	Level with the machine: the arm and pillar, which took 9 of every 10 blocked rays in the model. Beside your elbow: your right hand, the one feeding the fabric.	Zero clean positions for all seven lamps. Beside the right elbow the seam line looks lit but the 3cm guide mark falls to 67 percent under an Orsay, 8 percent under a Rousseau and 0 under an Aurelia: your feeding hand's shadow sits exactly on the marks you steer by.
Directly behind you	Your own chest, shoulders and head.	Zero clean positions for the Rousseau, Aurelia, Chandelle, Solara and Voltaire. Only the two long arcs get over your left shoulder from behind: the Cosmo from 30 to 120cm left and 90 to 120cm back, the Orsay from 50 to 90cm left at 90cm back.
Level with or behind the machine on the left	The machine head and arm, now between the shade and the fabric.	Zero clean positions for the Orsay and Cosmo, one for the Rousseau. Light from this side skims the plate at a low angle and the head roofs the work zone.

Clean = all five work zone points at least 70 percent lit and no bare globe in the sewer's eyes. 782 legal pole positions tested per lamp on a 10cm grid, the pole never inside the table or the chair.

What this means for each of our lamps

The shade heights and reaches below are the ones measured off the factory drawings in our arc reach guide, not the rounded listing figures. Pole positions are measured from the needle line (left) and from the needle toward your chair (back).

Lamp	Light source	Pole position that is clean	Verdict for a sewing table
Orsay Gold Arc	25cm open dome, rim 140cm, reach about 52cm	50 to 110cm left, 30 to 80cm back; also 50 to 90cm left at 90cm back	The pick. Widest clean band, all five points at 100 percent, and the white inside of the dome throws the most light on the seam of anything we stock.
Rousseau Rattan Weave	25cm linen inner drum, rim 134cm, reach about 26cm	50 to 70cm left, 20 to 70cm back	Works, beside your left elbow. The linen hides the globe, so no glare check needed.
Cosmo Chrome Arc	30cm open dome, rim 138cm, reach about 81cm	30 to 120cm left, 90 to 120cm back (behind your left shoulder)	Works from behind you only. Beside the chair the dome overshoots the table; from a metre behind, it arcs in over your forearm. Needs the floor space.
Aurelia Pleated	34cm pleated cone, rim 127cm, reach about 16cm	50cm left, 20 to 50cm back	Works, but only beside you: the rim sits below a seated head, so it can never pass over you. The listing says it is not one for detailed work; here it lights the fabric path, not the needle.
Chandelle Linen Column	16 by 40cm linen column, 127 to 167cm, no reach	50 to 60cm left, 20 to 60cm back	Works at about three quarters of the Orsay's light on the seam. A sideways glow, so keep it close and expect a softer edge.
Solara Fluted Lantern	Exposed globe in a 15cm fluted lantern, about 162cm	50 to 80cm left, 40 to 80cm back	Not for sewing. A small lantern 80cm above the plate puts about a third of the Orsay's light on the seam, and the bare globe sits in the upper edge of your view from every position in front of you. Its own listing calls it a mood lamp.
Voltaire 3 Light Cage	Three exposed globes, about 118, 133 and 144cm	50cm left, 50 to 70cm back	Not for sewing. Its lowest globe hangs at 118cm, and a seated sewer's eyes are at about 117cm. From a fifth of all positions that globe sits at eye level in plain view; turned away from you it stops lighting the work.

Set it up in five minutes

1. Thread the machine and put your hands where they sew. Sit as you really sit, leaning in, with a scrap of the fabric you use most under the foot. Test after dark with the room light as you normally leave it; daylight hides every shadow here.
2. Stand the pole 50 to 60cm left of the needle line, level with your left elbow. Measure from the needle, not the edge of the machine. With an arc, point the shade at the machine so it swings in over the table's front edge; with a column lamp, this is as far as it goes.
3. Check the shade's height against the plate. You want the open bottom of the shade 45 to 60cm above the needle plate. Our arcs are 46 to 59cm above a standard 81cm plate; if your table is a tall one, the band drops with it.
4. Look at the guide marks and the 10cm of fabric in front of the foot, not at the needle. If a shadow from your left hand crosses the seam line, the light is too shallow: move the base 10cm closer or raise the shade. If the marks right of the needle go dark, the light is too steep: move the base 10cm further out.
5. Glance up as you would to reach for the thread. If you can see the globe or the bright inside of the shade, slide the base 10cm back toward the chair so the shade's mouth sits beside your shoulder rather than in front of it. A dome at 140cm with your eyes at 117cm is only in view when it is close and in front of you.
6. Run the cable behind the table leg, never across the pedal. Your right foot lives under the table; the lamp stands on the left, so take the cable along the wall side of the table to the point. Our cable guide covers the rest of the room.
7. Mark the base with a piece of masking tape once it passes, so the lamp goes back to the same spot after vacuuming.

The globe

Every current lamp in our range takes a single E27 globe, not included, rated to 60W, which in practice means an LED of 8 to 12W. For sewing, two things matter more than the wattage. First, the shade: an open dome or a linen drum puts the light down on the work, a fluted glass lantern or a wire cage puts the globe in your eyes, and no globe fixes a shade that shows it. Second, colour. Most machines' built in lights are a cool white, so a warm 2700K globe in the floor lamp gives you two colours of light on the same piece of fabric, and thread that matched under one will look off under the other. If you match colours at the machine, a 3000K to 4000K globe in a closed dome like the Orsay reads truest; if the room is a bedroom first and a sewing room second, warm white and a second look in daylight is the honest answer. The trade offs are in our bulb temperature guide.

The limits of this model

It is one machine geometry, a domestic flatbed with a 12cm high, 17cm wide harp, and one seated posture with the hands either side of the seam line. If you guide fabric with your left fingertips right up at the foot, the point 3cm left of the needle will be in your hand's shadow from every position, which is why that point is reported but not scored. The light figures compare positions with each other, not with a light meter: an index of angle and distance, not lux. Tables lower than 73cm raise every angle a little and move the band outward by a few centimetres; the rule does not change.
