GE35 Double-Row Grow Light (GE35-100-B2 / GE35-120-B2D): One Light That Also Grows Tomatoes, up to 780 µmol/m²/s at 0.2 m

Overview

The GE35 double-row is Koray’s two-bar configuration of the GE35 family – official page ‘GE35 Family Indoor Planting Double Row Grow Lights’, with datasheet models GE35-100-B2 and GE35-120-B2D. Two parallel GE35 light bars are joined by two perpendicular cross bars into one system that lights a single wide bench, and the official copy sums up the point in five words: ‘one light can also grow tomatoes’. The page positions it for peppers, tomatoes, strawberries, succulents, pitcher plants and other sun plants – ‘family indoor cultivation of sun-loving plants’ – with high PPFD ‘to ensure cultivation effect’. This article leads with the double-row’s strongest indoor job: high-light fruiting vegetables, tomato and pepper, on one bench. All figures come from the official product page, the official datasheet page-1 render and the GE35 double-row datasheet PDF.

Key Specifications

System data from the official double-row datasheet (page 1) – identical values on the GE35-120-B2D and GE35-100-B2 spec-table rows of the official sheet.

The page adds a three-in-one dimming choice – 0-10 V / PWM / resistor – and notes that a non-dimming version can be chosen for lower cost; the datasheet table carries the 0-10 V and PWM comment on the B2D and ‘no dimming’ on the B2.

Two GE35 Bars, One Double-Row System

Officially, the system is two parallel GE35 bars joined by two perpendicular cross bars – on the B2D these are the power-input bar and the dimming bar (packing-list graphic ‘GE35-120-B2D Packing List’). System width 310 mm and height 55 mm; the bar length defines the model (995 mm for the B2, 1238 mm for the B2D). Each GE35 bar module carries two rows of LED chips – the featured photo above shows the double LED rows of one module under its clear cover.

On the dimmable B2D unit, a top-mounted control box carries the dimmer knob, the power switch and RJ ports labelled ‘PWM 0-10V Dimming’ – visible in the assembled-unit photo in this article. The official packing list names the kit contents: DM25 dimmer, ring-screw kit, steel-wire hanging rope with locks, RJ25 6P6C cable and AC power cord.

Up to 780 µmol/m²/s at 0.2 m: High PPFD for Fruiting Vegetables

High PPFD is the reason the double row exists. The GE35-120-B2D reaches 780 µmol/m²/s at 0.2 m (720 at 0.3 m, 410 at 0.6 m); the GE35-100-B2 reaches 770 / 710 / 380 at the same distances. Official PPF is 400 µmol/s for the B2D and 300 µmol/s for the B2, at 160 W and 120 W respectively. On the datasheet’s page-2 PPFD map, the B2D hung at 0.3 m covers a 0.5 x 1.2 m area – measured on a 60-point, 10 cm grid, dark room with no reflection – at an average of 462 µmol/m²/s. That is the intensity class behind the page’s claim that one light can also grow tomatoes indoors.

B2D Dimming Details: 0-10 V and PWM

For growers who want to step light levels through a season, the B2D datasheet gives concrete dimming numbers. With DIM+/- left vacant the unit runs at 100% of rated current; the non-dimming GE35-100-B2 covers fixed-output benches at lower cost.

• 0-10 V: minimum dimming depth of 0.5-10 V is 10%.
• PWM: dimming depth 10%; compatible PWM signal 400-3000 Hz, amplitude 10 V.
• Resistor (Rx): dimming depth 10%.

One Double Row over One Tomato Bench

The scene below follows the official use-case: one wide single bench of compact fruiting tomato plants under one GE35-120-B2D double-row unit – warm-white plus pink light, no multi-tier racks. The same one-light-per-bench logic applies to peppers and to other high-light sun-loving plants grown on a table top.

FAQ

Q: What is the GE35 double-row? A: Koray’s two-bar GE35 system: two parallel GE35 light bars joined by two perpendicular cross bars. Models: GE35-100-B2 (995 mm, no dimming) and GE35-120-B2D (1238 mm, dimmable).

Q: What does ‘one light can also grow tomatoes’ mean? A: Official page claim – one high-PPFD double-row fixture over a single bench can fruit tomatoes indoors (and peppers and other sun plants), without a multi-unit or multi-tier setup.

Q: GE35-100-B2 vs GE35-120-B2D? A: B2: 120 W, PPF 300 µmol/s, no dimming. B2D: 160 W, PPF 400 µmol/s, 0-10 V and PWM dimming. Both F175 spectrum, IP64, AC100~277V, PF > 0.9.

Q: What PPFD does it deliver? A: Up to 780 µmol/m²/s at 0.2 m (B2D; B2 770); B2D PPFD map at 0.3 m over 0.5 x 1.2 m averages 462 µmol/m²/s (dark room, no reflection).

Q: What spectrum does it run? A: F175 (graph on the official sheet); the page states the spectrum can be customized.

Q: Environment and certifications? A: Working -20 °C to 35 °C (double-row datasheet), lifespan 50,000 h (Ta 25 °C); CE / RoHS / FCC.
