Technical Specifications

Compatible & Equivalent Lamp References

This 38W 835 GR10q 4-pin 2D fluorescent lamp may be suitable as a replacement for equivalent lamps where the original fitting requires the same 38W rating, GR10q 4-pin base and compatible control gear.

Common replacement and cross-reference numbers include:

Philips Cross-Reference

A particularly useful replacement reference is:

Philips PL-Q 38W/835/4P – GR10q – 927939483540 – EAN 8711500271730

If your existing lamp is marked PL-Q 38W/835/4P, check that the GR10q base and physical dimensions correspond with your existing lamp.

Sylvania Cross-Reference

Another useful equivalent reference is:

Sylvania LYNX-QE 38W GR10Q 835 – Item No. 0025003

Sylvania identifies this as a 2D-shaped fluorescent lamp with a GR10q 4-pin base, 835 colour and approximately 10,000-hour average life.

The key replacement specifications for this product are:

38W • 835 • 3500K • GR10q • 4-Pin

Important: Manufacturer references are provided as a replacement guide. Always confirm the wattage, base, pin configuration and physical dimensions of your existing lamp before ordering.

Common Applications

The GR10q 2D 38W 4-pin fluorescent lamp is commonly used in compatible:

• Commercial ceiling fittings

• Bulkhead lights

• Hallways and corridors

• Stairwell lighting

• Emergency lighting

• Apartment and body-corporate common areas

• Offices

• Retail environments

• Schools and public buildings

• Utility areas

• Commercial washrooms

• Wall-mounted fittings

• Enclosed exterior fittings

The higher 38W output makes this lamp particularly useful in larger fittings and applications requiring more illumination than lower-wattage 16W, 21W or 28W 2D lamps.

How to Identify the Correct Replacement

Before ordering, check the markings printed on your existing 2D fluorescent lamp.

For this product, look for:

38W + 835 + GR10q + 4-Pin

You may also find markings such as:

38W/835/4P

PL-Q 38W/835/4P

LYNX-QE 38W GR10Q 835

or another manufacturer's equivalent model number.

What Does 835 Mean?

The 835 colour code identifies the lamp's colour characteristics.

8 = CRI approximately 80+

35 = approximately 3500K colour temperature

Therefore:

835 = CRI 80+ / 3500K White

3500K produces a balanced white appearance between warmer 3000K lighting and cooler 4000K fluorescent lighting.

GR10q 4-Pin – Important Compatibility Information

This product uses a GR10q 4-pin base.

Please check the base of your existing lamp carefully before ordering.

A similar-looking 2D fluorescent lamp with a different wattage or pin configuration is not automatically interchangeable, even if the overall square shape looks similar.

For this product, check:

✓ 38W

✓ GR10q

✓ 4-Pin

✓ 835 / 3500K

Also check the physical size of the lamp, particularly when replacing lower-wattage 2D lamps, as 38W 2D lamps are physically larger than many lower-wattage versions.

Do not choose a replacement based only on appearance.

3500K White Light

The 835 / 3500K White colour provides a balanced light appearance suitable for many commercial and general-purpose applications.

Common applications include:

• Commercial interiors

• Corridors

• Stairwells

• Apartment common areas

• Offices

• Retail environments

• Public buildings

• Utility areas

• General-purpose ceiling lighting

If maintaining the same light colour as your existing installation is important, check whether 835 or 3500K is printed on your old lamp.
