TECHNICAL FOCUS: PRODUCT IN DEPTH

We’ve reviewed a few large wash lights over the last year, and

I’ve wanted to take a look at the Coemar Infinity Wash XL for a

while. Logistics and timing never worked out but, finally, the stars

between Italy, Florida, and Texas aligned and one arrived in my

workshop for review.

Looking back, this is actually the first Coemar fixture I’ve

reviewed. Coemar is a well-known Italian manufacturer with an

extremely long pedigree in the automated lighting market. In

1984, the Coemar Robot was one of the very first automated

units to be commercially available and, although the company

didn’t invent the concept, it was a truly seminal product, largely

responsible for the burgeoning scanner market in the mid and

late 1980s.

All that’s history, of course, and Coemar, like many other

companies, has gone through significant changes since those

days. A few constants remain from the ‘80s; it is still in

Castelgoffredo in Northern Italy; Fausto Orsatti still designs its

products; and it still manufactures a wide range of units covering

markets from discos to touring.

The Coemar Infinity Wash XL (Fig. 1) is definitely in the latter

category—a 1,400W unit aimed at the top of the market. How

does it stack up against the other players in that sector?

As always in these reviews, we start at the lamp and work

through the optical chain, with measurements and descriptions

presented as objectively as possible as we go. The results are

based on the testing of one specific unit supplied by the

manufacturer as typical of the product. In this case, I was

supplied with a well-used-and-seasoned demo unit, so it should

be truly representative of real products in the field.

Although the Infinity Wash XL uses electronic switch mode

power supplies, it isn’t universal voltage, and the unit needs

manual setting of a voltage selector. The ranges are rather

narrow, with separate settings for 200/208V, 230V, and 240V (all

50/60Hz). The unit as supplied was set to 208V, which is the

normal three-phase U.S. voltage found in industrial premises,

including most theatres. However, in a U.S. domestic situation,

like my workshop, the supply is actually two-phase, not three, so

the intra-phase voltage is nominally 230V, which is more like the

European standard. Accordingly, for these tests, I set the unit to

its 230V setting.

As mentioned in prior reviews, the current crop of wash lights

typically fall into one of two distinct types—gated units, using

ellipsoidal reflectors, and full field units, using parabolic reflectors.

The Coemar Infinity Wash XL is one of the former, an ellipsoidal

unit with a gate.
