VerifiedUV™ 365nM Ultra Violet LED Strip 5mSKU: LED-2835-UV365-5M
Designed by Jon Cone and exclusively manufactured for InkjetMall. The verifiedUV™ high output 365nM UV strip is highest standards in terms of build and we believe the highest output product available. Using the latest generation of 2835 UV LED and configured 3 per inch.
*The irradiance has been verified using Ian Leake's latest LC+3 integrator to measure over 890 µW/cm² at a height of 4-6 inches above the target when placed in a squared grid. As a comparator using the same device, Cone Editions Press’ NuArc FT32V3UP 240v 30amp 3000 watt 32" exposure unit produces just over 1000 µW/cm² measured at the target.
The spread of the LEDs is 120 degrees and therefore it is possible to space them 8mm away from one another or 16mm away from one another, etc. The exposure times increase while the intensity striking the media decreases as the strips are placed further apart from one another.
The real benefit of this strip is running them adjacent to one another and taking advantage of super short exposure times. We also have easy to use strip connectors that fit the 8mm strip. At 14 watts 12v input per meter, these strip lamps will produce heat. We recommend as a best practice to peel the strip from the adhesive back and apply these directly to an aluminum sheet (1/8" is more than adequate) to transfer the heat from the strip to the back of the plate. If your exposure head is large, then a cooling fan for longer exposures may be recommended.
Further, we recommend that you wire these strips in rows in "series" rather than in parallel. Our strip connectors use teeth and can be separated into two sides, one each with a neg and a pos lead. These should be connected to terminal blocks. The blocks should be connected to the transformer. Always use the 80% rule with transformers. A 5 meter reel will use 70 watts of power, and the transformer should not be powered more than 80% of its rating. Therefore a 100 watt transformer should be used. If you use 10 reels (50 meters) the wattage increases to 700 watts and a transformer of at least 875 watts should be used.
Wiring in series prevents voltage drop. Likewise, using heavier gauge wire from the transformer to the terminal blocks prevents voltage drop. By example, the Cone Editions Press exposure head uses 150 rows totaling 171 meters requiring 2,400 watts and utilizes three 1,000 watt transformers. Each 1,000 watt transformer powers 50 rows. The 50 rows positive + (red) leads all terminate into 50 terminal blocks which are interconnected. Likewise, the 50 rows of negative - (black) leads all terminate into 50 terminal blocks which are interconnected. The positive terminal blocks are connected to the 1,000 watt transformer via 16AWG wire, and the negative terminal blocks are connected with a 16AWG wire. In this manner, voltage drop is negligible.
Although connecting strip to strip seems easier and more logical, by doing so in parallel with one another, the first strip voltage will be considerably higher then the last strip's voltage and results will be uneven luminosity from the first to the last strip.
You get one reel, 5 meters in length, with a dual wire connector at one end.
These strip reels require 12v. They require 14 watts 12v per meter.
