For a 4-watt T5 fluorescent lamp, the closest matches in this selection are the OHLECTRIC F4T5/D and the 6-inch F4T5/CW: both are 4 watts, have a G5 bi-pin base, and are listed at 75 CRI—not 62. Check the fixture’s lamp length, color temperature, and ballast requirements before buying. The other three options are higher-wattage T5 tubes, so they are included for comparison but are not substitutes for a 4-watt lamp.
| Product | Wattage | Listed CRI | Best For |
|---|---|---|---|
| OHLECTRIC F4T5/D | 4W | 75 | Six-inch daylight replacement |
| F4T5/CW Fluorescent Tube | 4W | 75 | Lanterns and small fixtures |
| amgolibi F21T5/841 | 21W | 82+ | Longer 34-inch fixture |
| Konideke F54T5/850/HO | 54W | 82 | High-output, 46-inch fixture |
| Sunlite F54T5/850/HO | 54W | Not stated | Bulk purchase of high-output tubes |
OHLECTRIC F4T5/D 4-Watt Daylight Tube
This six-inch straight tube is the closest match for buyers seeking a compact 4-watt T5 lamp. Its listed specifications include a G5 bi-pin base, 6500K daylight color, 130 lumens, 75 CRI, a glass tube, and a stated 5,000-hour life. It is sold as a four-pack.
Best for: Buyers replacing a short 4W tube who want a daylight color. It was selected because its wattage and compact T5 format align with the search intent. Limitation: Its CRI is 75, not 62, and its 6500K color may not suit buyers seeking warmer light.
F4T5/CW 4-Watt Cool-White Tube
This four-pack is specified as a 6-inch, 4W fluorescent tube with a 4100K cool-white color, 130 lumens, 75 CRI, and a G5 medium bi-pin base. The listing gives a 5,000-hour life and describes it for under-cabinet lighting, basements, utility rooms, garages, and camping lanterns.
Best for: Buyers who need a short 4W tube and prefer cool white over 6500K daylight. It was selected as a direct wattage-and-size match. Limitation: The stated CRI is 75 rather than 62; confirm the 6-inch length and base against the original lamp.
amgolibi F21T5 34-Inch Tube
This product is a 21W T5 tube measuring 34 inches, with a G5 mini-bi-pin base, 4100K cool-white light, 2,000 lumens, and a listed CRI of 82+. It comes in a six-pack.
Best for: Buyers replacing a longer 21W tube who value the listed CRI above 80. It is included as a T5 comparison, not as a 4W substitute. Limitation: Its wattage and length differ substantially from a six-inch 4W lamp.
Konideke F54T5 High-Output Tube
This 25-pack contains 46-inch, 54W F54T5/850/HO tubes with a G5 base. The listing specifies 5000K color, 4,200 lumens, and CRI 82.
Best for: Buyers who need a long, high-output lamp and want a stated CRI above 80. Limitation: At 54 watts and 46 inches, it is not an appropriate replacement for a 4W, six-inch tube.
Sunlite F54T5 54-Watt Tube
This 40-pack is described as a four-foot, 54W high-performance T5 tube with a G5 mini bi-pin base, 5000K daylight color, and 5,000 lumens. The provided product details do not state its CRI.
Best for: Buyers replacing many compatible four-foot, 54W lamps. Limitation: Its four-foot length and 54W rating make it a clear mismatch for a 4W fixture, and a CRI value is not provided.
Buying Guide: How to Choose a T5 Fluorescent Lamp
Does a 4-watt lamp with CRI 62 need an exact match?
The listed products do not include a 4W lamp rated at CRI 62. The two 4W options specify CRI 75. If an exact color-rendering value matters, verify the replacement’s manufacturer specification rather than assuming that a similar wattage or color temperature means the same CRI.
What should you check before ordering?
- Wattage: Match the lamp rating required by the fixture. A 21W or 54W tube is not a 4W replacement.
- Length: Compare the listed tube length with the old lamp and available fixture space.
- Base: These products list G5 bi-pin bases, but confirm the pins and socket fit your fixture.
- Color temperature: 4100K is described as cool white; 6500K and 5000K are daylight options in these listings.
- CRI: Choose based on the stated value if color appearance matters. A higher CRI is not a substitute for matching lamp size and electrical requirements.
