Question 1

How does the GL K2 PRO differ from the GL4612 PRIME?

Accepted Answer

Both are compact 0.72W modules designed for shallow letters. The GL K2 PRO uses a Philips 2835 chip with IP68 (continuous submersion) and a 170° beam in a 46 × 15 mm body. The GL4612 PRIME uses an SMD 2835 chip with IP67 (temporary immersion) and a 120° beam in a 46 × 12 mm body — 3 mm lower profile. Choose the K2 PRO for Philips chip quality, IP68 certification and the wider 170° beam; choose the GL4612 for the absolute minimum module height.

Question 2

What letter depths is the GL K2 PRO suited for?

Accepted Answer

The GL K2 PRO is optimised for shallow to medium channel letters with return depths from approximately 30 mm upward. Its 46 × 15 mm compact body fits letter geometries where the GL K8 PRO (69 × 19 mm) is too large.

Question 3

Why does the GL K2 PRO use a Philips 2835 chip?

Accepted Answer

The Philips 2835 chip carries tighter forward-voltage binning and tighter colour tolerance than commodity SMD 2835 chips. This results in more consistent illumination across large signs and better lumen maintenance over a 50,000-hour rated lifespan. The GL K2 PRO brings this chip quality to compact shallow-letter applications.

Question 4

What is the difference between Warm White 3000K and Cool White 6500K?

Accepted Answer

Warm White 3000K produces a soft, rich tone suited to hospitality, luxury retail and premium shallow letter signage. Cool White 6500K produces a crisp, high-visibility output preferred for corporate and retail channel letters. Both variants are identical in all technical specifications.

Question 5

How many modules can I wire in a single run?

Accepted Answer

Maximum 50 modules per 12 V series run (36 W total). For large signs, use multiple parallel circuits from the driver.

Question 6

What power supply size do I need?

Accepted Answer

Multiply the module count by 0.72 W, then divide by 0.8. For 20 modules: 14.4 W ÷ 0.8 = 18 W minimum. A 20 W or 30 W 12 V constant voltage driver provides safe headroom.

Question 7

What does IP68 mean and when is it required?

Accepted Answer

IP68 is the highest standard waterproof rating, covering continuous and indefinite submersion. It is required for ground-level signs at persistent flood risk, coastal salt-spray locations, and any location where the sign interior may fill with water. For most standard outdoor shallow letter signs, IP67 is sufficient — but IP68 provides the highest possible assurance.

Question 8

Does the GL K2 PRO carry a warranty?

Accepted Answer

Yes — 5 years from date of purchase when installed in accordance with Glowfy's technical guidelines and powered from a compliant 12 V DC constant voltage driver. The 5-year warranty applies across the full PRO range.
