my project design of bulkhead luminaire
time frame : 6 weeks product domain : general lighting, surface mounted luminaire area of use : industry, maintenance areas, domestic need : recent venture into infrastructural projects outdated product needed to be phased out contemporary light sources
introduction
history the term
A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines, to contain flooding. A bulkhead is the physical partition that divides an airplane into different classes or sections. Typically, a bulkhead is a wall but can also be a curtain or screen
the starting point
“Fig. 60 shows another form of bulkhead fitting designed to economize lamps. As will be understood, it is fixed in a hole cut in the bulkhead to receive it, say between two cabins, the flange shown being screwed to the woodwork, and the light showing on either side. This fitting is most frequently used where a permanent light is required. It would hardly do for cabin lamps, except in special cases—as, though it could be arranged for a switch in either cabin to turn on the light, neither could turn it off if the switch in the other cabin was closed, which would hardly be convenient for an officer who wanted to turn in during his watch below, if his light happened to belong to the next cabin too, and the owner of that cabin to want the light burning.”
Marine Engineers” (1892)
- Walker, Sydney F.: “Electric Lighting for
present status
A bulkhead luminaire is typically a strong, robust industrial lighting fixture which is used as a low cost, general purpose luminaire.

research phase
PHILIPS NXC 101/ FXC 101 pros • sturdy build quality. better finishing due to pressure die casting • cover retaining ring makes it look neat and adds better pressure on gasket •tighter fitting gasket adds to cleaner look and uniform sealing • robust proportions, consistent with industrial aesthetic • high IP rating (IP 65) makes it ideal for industrial usage • same luminaire for CFL and GLS lamps (only ballast mounting tray added for CFL ) • powder coated wire guard looks more elegant, more precise manufacturing cons • comparatively difficult to maintain and service • bulky, machine like aesthetic makes it unsuitable for domestic use • mounting detail may create instability • higher cost • concave shaped base of housing could have become a reflector if ballast was better accommodated • clear PMMA cover looks flimsy, fragile. thermoforming doesn’t allow good finishing (compared to injection molded)

HAVELLS RUGBY
pros • finer build quality. better finishing even from gravity die casting • cover retaining ring integrated with wire guard looks more elegant, more precise • smaller dimensions and slimmer proportions fits well into domestic use • same luminaire for CFL and GLS lamps, versatile • concave base of housing, painted white on inner surface, acts as reflector • cover retaining frame requires only 2 screws to open • have accomplished graduation into a wall light segment, without adding cost cons • white color difficult to maintain • mounting detail through the housing requires full disassembly • restricted to domestic use due to size (visual bulk/robustness lacking) and IP 43 rating • requires retrofit CFL, can accommodate only 8W • CFLs should be given importance if domestic market is the focus

Bajaj BJBE 19 pros • deep drawn housing is a distinguishing factor ( innovative approach ), also enables smoother finish on housing • BJBE has step in body to accommodate gasket neatly • tighter fitting gasket adds to cleaner look and uniform sealing • robust rectangular form looks contemporary • only 2 screws require opening for lamp replacement • specifically made for CFLs, hence dimensionally appropriate cons • higher initial cost (as with all CFL luminaires) • mounting through back wall requires full disassembly • lack of wire guard breaks association with bulkheads (one associates it with wall lights) • prismatic glass pattern is passé. more contemporary look needed • wire management requires improvement

Wipro WKG13 pros • hinge detail in wire guard allows great ease of lamp replacement • consistent with industrial aesthetic • wall mounting details add greater stability when mounted • low cost cons • poor precision ( tolerances ), manufacturing quality and finishing • gasket unevenly held by wire guard causes low IP rating ( 43 ) and makes entire product look crude • holder attachment and wiring details are crude • “mechanical” detailing but proportions look “domestic”. doesn’t look “heavy-duty” • overall crude appearance and poor quality do not befit a brand like Wipro.
significant features
Wipro WKG14 pros • contemporary look and materials • polycarbonate cover doesn’t require wire guard • slimmer sleeker proportions, more appropriate for CFLs • higher tolerances and tighter fits put it in a different league as far as perceived quality goes • ease of lamp replacement (2 screws) • much better gasket material (silicon), and tighter fit enable higher IP (54) • graduation into wall light segment. cons • due to plastics used, it may not meet regulations in infrastructural applications • mounting requires full assembly on the spot, may not be suitable for locations such as service chutes, etc as installation points are difficult to reach • higher cost, due to included ballast • lack of wire guard breaks association with the name “bulkhead”
