RAB HIDFA-120S-EX39-8CCT-BYP/5SP – Frequently Asked Questions

1) Will the RAB HIDFA EX39 LED lamp work in my existing HID fixture without rewiring?
No, not without rewiring. The HIDFA EX39 is a ballast bypass lamp, which means the existing HID ballast has to be removed or bypassed and line voltage wired straight to the socket. Once that's done it runs on 100-277V, so it drops into standard commercial and industrial circuits without a voltage-specific version. Budget an electrician's time per fixture, not just a lamp swap.
2) What wattages does the RAB HIDFA EX39 come in, and how do I pick one to replace a 400W metal halide?
Eight orderable wattage steps, each one field-selectable across three settings: 27/18/12W, 36/27/18W, 45/36/27W, 54/45/36W, 63/54/45W, 100/80/63W, 120/100/80W, and 205/165/135W. Pick by the lumen output you need rather than by matching HID wattage one for one, since LED delivers far more usable light per watt. The 205/165/135W version is the top of the range and is the one specified for the largest HID retrofits.
3) Can I change the color temperature on the RAB HIDFA lamp after it is installed?
Yes. The HIDFA carries 8CCT field-adjustable color selection, set on the lamp itself, so a facility can standardize a warmer color in a lobby and a cooler one in the warehouse from the same stocked part number. For a property manager or MRO buyer that means one SKU on the shelf instead of eight, and it means a color mismatch found after install is a setting change rather than a return.
4) Is there a mounting orientation restriction on the RAB HIDFA EX39 lamps?
One of the eight is orientation-specific: the 205/165/135W version is designated Vertical. The remaining seven wattage steps, 27/18/12W up through 120/100/80W, carry no orientation designation. If you are retrofitting horizontally mounted wallpacks or shoebox fixtures, that vertical-only note on the largest lamp is the detail to check against your fixture before ordering.
5) Should I retrofit with an HID replacement lamp or replace the whole fixture?
A bypass lamp like the HIDFA makes sense when the housing, lens, and reflector are still sound and you mainly want the ballast out of the maintenance picture. Once the ballast is bypassed there's no ballast left to fail, and the lamp is rated 50,000 hours. Where the housing is corroded, the lens is clouded, or the optics are wrong for the space, a new fixture is the better spend, because a lamp swap cannot fix distribution. The retrofit path also keeps the work inside a fixture-by-fixture schedule rather than a full re-mount.
6) Do the RAB HIDFA lamps come in multi-packs or as single lamps?
Both, depending on wattage. The 36/27/18W, 45/36/27W, 54/45/36W, 63/54/45W, 100/80/63W, and 120/100/80W versions carry a /5SP suffix on the part number, indicating a 5-pack. The 27/18/12W and the 205/165/135W vertical version have no pack suffix. On a large retrofit that difference changes your order quantity math, so count in packs not lamps for the six that ship that way.
7) Are RAB HIDFA LED lamps suitable for areas with cameras or machinery where flicker matters?
Flicker is rated under 30 percent, driven by a constant current driver. That is a stated figure rather than an inference, which matters in warehouses with security cameras or rotating equipment where visible flicker and stroboscopic effect are real complaints. For a spec that calls out a specific flicker percentage or a low-flicker classification, check the number against the requirement on the drawing.
8) Is the RAB HIDFA a clear lamp or a frosted one?
Clear. That keeps the source more directional, which is what you want when the existing fixture has a reflector doing the work of aiming the light. In an open high bay or an aisle-lit warehouse that's the right choice; in a fixture where the lens is the only diffusion, expect a more visible source than a frosted lamp would give.
