GE Lighting Replacement Checklist: 7 Steps I Use Before Any Commercial LED Order (After $11K in Mistakes)

I handle commercial lighting orders for a mid-size distributor. Nine years in, and I've personally made (and documented) 6 significant sourcing mistakes totaling roughly $11,400 in wasted budget, redo costs, and expedited shipping. Now I maintain our team's pre-order checklist so nobody repeats them.

This isn't a product guide. It's the exact 7-step checklist I run before any commercial LED order ships — whether it's GE Lighting HID replacement LED corn cob bulbs, GE Lighting Reveal HD LED, spotlight OEM runs, or private label recessed fixtures. If you're a wholesaler, specifier, or OEM buyer, you can copy this directly.

Seven steps. Maybe 25 minutes per order. That 25 minutes has saved us more than the $11,400 it cost to learn.

Who This Checklist Is For

• You're sourcing LED fixtures or replacement lamps for a project, a catalog, or a private label line
• You deal with mixed catalogs — legacy HID sockets, retrofit lamps, and new-build LED fixtures in the same order
• You can't afford a full container redo because someone assumed a base type

If you're a homeowner buying one bulb, this is overkill. If you're buying 200+ units or running an OEM program, every step here applies.

Step 1: Audit the Existing Socket and Ballast Before Anything Else

This is the step most people skip, and it's the one that cost me the most.

In March 2021, I quoted a 400-unit GE Lighting HID replacement LED corn cob order for a warehouse retrofit. Customer said "medium base." I didn't verify. What they actually had was mogul base (E39) with probe-start metal halide ballasts. Four hundred lamps, wrong base, wrong ballast assumption. That order came back on our dock and cost about $4,800 between return freight, restocking, and the rush replacement. (Should mention: the customer's own maintenance guy gave me the wrong info — but that's on me for not asking for a photo.)

Here's what to physically confirm before quoting:

1. Base type: E26 (medium) or E39 (mogul)? A tennis ball fits an E39 socket. If it doesn't, it's E26. Crude, but it works.
2. Ballast type: Magnetic probe-start, magnetic pulse-start, or electronic? LED corn cobs are almost always ballast bypass (direct wire). If the customer expects plug-and-play, you need a ballast-compatible lamp instead — different SKU entirely.
3. Voltage at the socket: 120V, 277V, or 347V? Commercial high-bays are frequently 277V. I've seen a 120V-only lamp spec'd into a 277V circuit because nobody checked.
4. Enclosed fixture or open air? This determines whether you need an enclosed-rated lamp. Heat buildup kills standard corn cobs in sealed fixtures.

Get a photo of the socket and the ballast label. Every time. No exceptions. I don't care how long you've worked with the customer.

Step 2: Lock Down Color Temperature, CRI, and Distribution

This is where GE Lighting Reveal HD LED conversations usually start, and where they go wrong.

Reveal HD is a retail-facing line — high CRI, clean color rendering. If you're specifying it into a commercial retrofit or trying to source an OEM equivalent, the specs that matter are:

• CCT: 3000K, 3500K, 4000K, or 5000K. ANSI C78.377 defines the nominal CCT and tolerance ranges — a "4000K" lamp can legally sit anywhere in a defined chromaticity quadrangle, and side-by-side, two different 4000K lamps from different factories can look visibly different.
• CRI (Ra): Standard commercial is 80+. Retail and hospitality usually want 90+. Reveal-style products push higher. If your customer's expectation is "it should look like the Reveal bulb," an 80 CRI OEM equivalent will disappoint them.
• Beam distribution: Corn cobs are omni-directional by nature — fine for high bays and post-tops, bad for anything aiming at a wall or a product display. Track and spotlight OEM work needs defined beam angles (15°, 24°, 36°). Don't let a sourcing agent talk you into a corn cob for an accent application.

I wish I had tracked color complaints more carefully from the start. What I can say anecdotally is that roughly a third of our post-installation complaints trace back to CCT or CRI mismatch, not to actual failures. That's a spec problem, not a product problem.

Step 3: Confirm Ballast Bypass vs. Ballast Compatible (The One That Bites Everyone)

Most HID replacement LED corn cobs are ballast bypass. That means:

• The existing ballast gets removed or disconnected
• Line voltage wires directly to the socket
• An electrician has to do it — it's not a screw-in swap

If nobody told the customer that, you will hear about it. I've been on that call. A 60-unit order shipped to a facility where the maintenance team expected to just screw in lamps. Labor quote came back at over $2,000. Guess who ate the difference.

There are ballast-compatible LED options (they work on specific magnetic ballasts without rewiring), but they're a narrower product category, more expensive, and less efficient. If your customer wants "just swap the lamps," that's the conversation you need to have before the PO, not after.

Checkpoint: Write the install method on the quote in plain language. "Lamps require ballast bypass. Electrician required." Then have the customer acknowledge it in writing.

Step 4: Do the Lumen Math Honestly

Everyone compares wattage. Nobody compares delivered lumens, and that's how you get a callback.

Quick reference for HID replacement:

• 400W metal halide ≈ 36,000–44,000 initial lumens, but loses 30–40% over life with lumen depreciation
• A 150W LED corn cob typically delivers 20,000–24,000 lumens — and holds almost all of it
• A 200W LED corn cob in the 26,000–30,000 lumen range is often the honest match for a 400W MH that's near end of life

If you promise a 1:1 wattage replacement, you'll under-light the space. If you promise 1:1 lumens on day one, you'll actually be fine — because the HID was never delivering its rated output by the time you showed up.

I don't have hard data on every manufacturer's lumen maintenance curves. What I can tell you is: ask the supplier for LM-80 data and the TM-21 projected L70. If they can't produce it, that's a supplier problem, not a product problem.

Step 5: Decide — OEM or Private Label? (They're Not the Same)

This is the question in every commercial lighting catalog conversation, and most people blur the two.

• OEM: You're buying a factory's existing product, possibly with minor customization (housing color, CCT options, wattage, connector). Their tooling, their certifications, their form factor. You add your branding if your volumes justify it. Fast, lower MOQ risk, less differentiation.
• Private label: You're putting your name and specs on a product — often off the same production line — and you own the label, the packaging, and the after-sales commitment. The product still isn't truly yours; the liability and brand risk is.

The trap: buyers assume "private label" means custom tooling. It usually doesn't. If you need a genuinely custom spotlight OEM fixture — different optic, different housing, different connector — that's a tooling conversation with a real MOQ (often 1,000–3,000 units minimum) and a real NRE cost. Private label with a standard fixture is a sticker and a box.

Don't pay custom-tooling prices for a sticker. Don't expect custom-tooling results from a sticker.

Step 6: Verify the Vendor's Certifications and Test Documents

Before any order over $5,000, I request:

1. UL or ETL listing on the actual product model — not the parent company's general listing
2. DLC listing status if the project touches any utility rebate program. Lots of commercial jobs rely on DLC rebates to hit the customer's budget. If the fixture isn't listed, the rebate's gone and so is the deal.
3. LM-79 test report for the specific SKU (not a similar one)
4. LM-80/TM-21 data for the LED package
5. FCC and RoHS documentation for the control gear if it's a smart or networked fixture

This is where I got burned in 2022 — a fixture passed my visual inspection, then failed UL because the driver in the production run was different from the driver in the sample. Same model number, different BOM. Cost about $1,900 in expedited re-orders and a delayed install.

Ask for the driver brand, the LED brand, and the model numbers of both. If the supplier gets evasive, that's your answer.

Step 7: Run the Pre-PO Final Check

Before the PO goes out, I run this on one page:

1. Base type verified with photo: ☐
2. Voltage verified (120V / 277V / 347V): ☐
3. Ballast bypass or compatible — written on quote: ☐
4. CCT, CRI, beam angle, lumens — matched to application: ☐
5. Enclosed-rated if needed: ☐
6. UL/ETL model number matches the SKU being ordered: ☐
7. DLC status confirmed if any rebate is involved: ☐
8. OEM vs. private label scope defined in writing: ☐
9. Lead time and shipping terms confirmed with timestamp: ☐
10. Customer acknowledgment of install requirements: ☐

We've caught 47 potential errors using this checklist in the past 18 months. Some of those were small — wrong connector, wrong carton label. A few would've been $3,000+ problems. I'll take the 25 minutes.

Notes and Common Mistakes

A few things that don't fit neatly in the steps above but keep showing up:

Don't trust a catalog photo for color-critical decisions. Screens lie, and CCT renders differently on every monitor. Get a physical sample or a real spectroradiometer reading for anything above $10K.

"GE compatible" is not "GE." If your customer is asking for GE Lighting replacement products specifically — for warranty, for spec, for brand trust — an OEM equivalent is a different product. Say so up front. Retrofitting a substituted product into a spec that named GE is a change order waiting to happen.

Lead times drift. The lead time confirmed in January is not the lead time in April. Re-confirm two weeks before the ship date, every time. (I want to say we learned this the easy way, but we didn't.)

This worked for us, but our situation is specific. We're a mid-size domestic distributor with predictable ordering volumes and a small, experienced QC team. If you're a startup doing one-off container orders, or a large OEM with automated POs, your checklist will look different. The principles hold; the mechanics may not.

The industry has changed a lot on this front. What was best practice in 2018 — paper spec sheets, dealer-trusted catalog skus, tacit assumptions about compatibility — doesn't survive contact with a 2025 supply chain. But the fundamentals haven't changed: verify the socket, verify the ballast, verify the documents, and put the install requirement in writing. Everything else is detail.
