## Description

_Source: Configurator page (intro) — https://betacalco.com/component/configbox/mtIIsurface/configurator#top-part_

The triangular shape is a powerful way to create an edgy and energetic aesthetic. With a super-slim 1” profile and 3 sizes ranging from 2’ to 4’, MICRO TRIANGLE II is ideal for offsetting symmetrical layouts. The light uniquely emits from the inner side of the frame and can be coordinated with MICRO TRIANGLE SE which offers direct/indirect light. For a whimsical style, combine MICRO TRIANGLE with MICRO RING or MICRO QUAD. Available in a multitude of distinct finishes, this statement piece adds refinement and sophistication to your space.

### Performance lookup by configuration code

The "lookup_rows" are matched against a configuration by code segments: the first row whose segments are all present in the configuration code applies (a subset match). If a multiplier row matches too, both lumen figures are scaled by it and lumens-per-watt is recomputed. Sections, decorative sections and TM-30 blocks are static per product and do not depend on the configuration.

| Code segments | Lumens direct | Lumens indirect | Watts | Lumens/W |
|---|---|---|---|---|
| MTTC1C24 / LPF021 | 1300 | 0 | 10 | 128 |

## How the configuration code is built

_Source: Configurator page (the configurator) — https://betacalco.com/component/configbox/mtIIsurface/configurator#configurator_

The configuration code is the answer codes of the questions below, in this order, joined by "/". A question that is not answered contributes its default code when it has one, otherwise nothing. Answers marked "(none)" contribute nothing. Questions that create sub-positions (accessories quoted as their own line) are not part of the code.

| # | Question | Default code | Luminaire code |
|---|---|---|---|
| 1 | Luminaire (id 5764) |  | yes |
| 2 | Lumens/ft (id 5765) |  |  |
| 3 | CRI (id 5767) |  |  |
| 4 | CCT (id 5768) |  |  |
| 5 | Voltage (id 5769) |  |  |
| 6 | Dimming (Remote) (id 5770) |  |  |
| 7 | Finish (id 5771) |  |  |
| 8 | Emergency (id 5772) |  |  |

## Configurator: questions and answers

_Source: Configurator page (the configurator) — https://betacalco.com/component/configbox/mtIIsurface/configurator#configurator_ · _Source: Full specification sheet (PDF, imperial) — https://betacalco.com/specsheets/mtIIsurface/full/imperial_

Questions are listed in the order they appear. Answer codes are the code segments that make up the configuration code. IDs are the identifiers the configurator uses (question id = element id, answer id = option-assignment id).

Some questions and answers are only available in certain combinations of other answers. Those availability rules are not listed here; the JSON document carries them per question and per answer (`visible_when` as a sentence, `visible_when_rule` as the raw rule).

1 page(s), 8 question(s), 36 answer(s).
