Description
PHILIPS GreenPerform Explosion Proof EX68X Series
Four explosion proof luminaire types — high bay, floodlight, platform light and tri-proof batten — for Zone 2 gas and Zone 21/22 dust areas in oil and gas, chemical, pharmaceutical, shipyard and heavy equipment plants. 20 W to 450 W, 140 lm/W, IP66 and IK08.
EX68X20-450 WIP66 / IK08Ex ec IIC T6...T4 GcEx tb IIIC T85...T105 °C Db46 codes
140 lm/WMaximum efficacy of the high bay, floodlight and tri-proof types
IP66Sealing, plus IK08 impact resistance on all four types
T6Lowest gas class, surface below 85 °C at the T6 rating
46Ordering codes in 4000K and 6500K, four families
All four share one dual marking and one electrical platform, so a plant can standardise on one driver and one spare-part list.
Choose the lamp type before the wattage
These are not four wattage variants of one body: material, optics, mounting interface and design height differ. Pick the type from the mounting point, then the wattage from the study.

The four bodies in the range
Three types use die-cast aluminium with a toughened glass cover; the batten uses a polycarbonate body so a 1200 mm length stays light enough for one installer. All are powder coated to RAL 7040, pre-wired.
What the nameplate actually allows
Two markings, one for gas and one for dust. Both are read against the zone drawing of the plant before ordering.
II 3G Ex ec IIC T6...T4 Gc (gas, Zone 2)
II 2D Ex tb IIIC T85°C...T105°C Db (dust, Zone 21 and 22)
| Zone | EPL | What happens there | EX68X |
|---|---|---|---|
| Zone 0 | Ga | Gas present continuously | Not rated |
| Zone 1 | Gb | Gas likely in normal operation | Not rated |
| Zone 2 | Gc | Gas unlikely and short lived | Rated |
| Zone 20 | Da | Dust cloud present continuously | Not rated |
| Zone 21 | Db | Dust cloud likely in normal operation | Rated |
| Zone 22 | Dc | Dust cloud only in abnormal conditions | Rated |
IIC is the most easily ignited gas group, so an IIC luminaire may also be used where only IIA or IIB gases occur. T6...T4 means the surface stays under 85 °C at T6 and under 135 °C at T4, covering gases that ignite above 135 °C.
Temperature classes and why T4 to T6 matters
| Class | Max. surface | Gases it protects against (ignition above) |
|---|---|---|
| T1 | 450 °C | Hydrogen and most process gases |
| T2 | 300 °C | Acetylene, ethylene |
| T3 | 200 °C | Petrol and light fractions |
| T4 | 135 °C | Acetaldehyde |
| T5 | 100 °C | Carbon disulphide |
| T6 | 85 °C | Ethyl nitrate, the strictest class |
Most codes can be declared at T6, so one body covers the strictest gas class too. The declared class is confirmed on the label of the ordered code.
Where the cost of the luminaire went
01
Oversized die-cast cavity
Internal volume, electrical clearance and creepage sit well above the minimum. The driver compartment runs cooler and the gasket is not heat soaked, so it holds IP66 for the service life.
02
Lumileds chips, IP67 driver
Lumileds packages on a metal-core board driven by a Sangsun isolated IP67 driver. 1-10V dimming is standard, and the 450 W floodlight also accepts 0-10V.
03
Gas and dust in one body
Ex ec for Zone 2 gas plus Ex tb for Zone 21 and 22 dust: one stock item, one installation procedure, no separate dust-rated range on the shelf.
04
Reports and finish
CCC, GB3836 and IEC60079 reports, LM79, EMC, RoHS and REACH. 500 hours salt mist on RAL 7040 powder coating, five cable entries on the high bay. CB and CE planned end 2026, ATEX and IECEx in progress.
Three duty profiles
Refining and petrochemical
Pipe racks, distillation structures, loading towers: EX689W for long throws, EX688P over pump houses.
Refinery process area: EX689W floodlights and EX688P high bays on pipe rack structures.
Chemical and pharmaceutical
Zone 21 and 22 filling rooms, drum stores, reactor platforms: EX686C along the lines, EX687P on walkways.
Pharmaceutical suite: EX686C battens for dust-rated Zone 21 and 22 filling rooms.
Marine and heavy equipment
Deck, crane and helideck lighting on offshore units and shipyards: EX689W at 250 W to 450 W, 500 hours salt mist, 10 kV surge.
Offshore platform: EX689W floodlights for deck, crane and helideck perimeter lighting.

Fixing, entries and the rules that void the certificate
| Type | Mounting | Detail |
|---|---|---|
| EX688P | Ceiling, side, suspended | Direct ceiling fixing or U-bracket side mounting; NPT 3/4 entry for a rod; five cable entries, four side, one top. |
| EX689W | Yoke bracket, pole, suspended | U-bracket supplied, locking teeth hold the aiming angle; NPT 3/4 entry; codes from 420 W use the larger 420 × 300 × 251 mm body. |
| EX687P | Lifting and ceiling | Wire guard fitted as standard; 140° distribution suits low mounting heights; NPT 3/4 entry with an optional bracket. |
| EX686C | Ceiling surface | Stainless clips on a flat surface, 1 m pre-wired cable, no separate accessory; the 1246 mm body needs fixings at both ends. |
Before energising: isolate the circuit before opening any cover. Cable glands and blanking plugs must be Ex-rated; an uncertified gland voids the declared marking. Do not drill extra entries, and close unused entries with their certified plugs to hold IP66. Installation follows IEC 60079-14 and the zone drawing of the plant.

Frequently asked questions
What does the marking Ex ec IIC T6...T4 Gc mean on an EX68X luminaire?
It is the gas-atmosphere marking of the luminaire. Ex ec is increased safety, the protection concept accepted for Zone 2. IIC is the gas group with the lowest ignition energy, so an IIC rated luminaire may also be installed where only IIA or IIB gases occur. T6...T4 is the temperature class range: the surface stays below 85 °C in the T6 case and below 135 °C in the T4 case. Gc is the equipment protection level that corresponds to Zone 2.
Which hazardous areas are the EX68X luminaires certified for?
Gas: Zone 2 only, equipment protection level Gc, for IIA, IIB and IIC gases. Dust: Zone 21 and Zone 22, equipment protection level Db, for IIIA, IIIB and IIIC dusts, with a maximum surface temperature of T85 °C to T105 °C. The series is not rated for Zone 0, Zone 1 or Zone 20, and the zone classification of the plant always takes precedence over the marking.
High bay, floodlight, platform light or tri-proof: which type should I order?
Choose EX688P for indoor heights above roughly 6 m such as reactor bays and high racking. Choose EX689W when the mounting point is outdoors or on a structure that needs an aimed beam, from 50 W walkways up to 450 W towers. Choose EX687P for platforms, corridors and small rooms where a 140° wide distribution at 30 W or 60 W is enough. Choose EX686C for linear runs along racks, conveyor lines and low ceilings in 600 mm or 1200 mm bodies.
Are ATEX and IECEx certificates already issued for this series?
The nameplate carries the IECEx and ATEX marking format. The certificate package available today covers CCC, the Ex certificate for the EX689W floodlight, GB3836 and IEC60079 test reports, LM79 photometric reports and EMC. CB and CE certification is planned for the end of 2026, and ATEX and IECEx certification is in progress. Ask for the current report set before a tender closes.
What supply and control does the series need?
All types run on 100-277 V AC, 50/60 Hz, power factor at or above 0.95 and THD at or below 20% at 220 V AC, insulation Class I. Dimming is 1-10V across the series, and the 450 W floodlight also accepts 0-10V. Flicker is held to PstLM at or below 1 and SVM at or below 0.4, and 10 kV line-to-earth surge protection is built into the driver compartment.
