Product Overview
GE CMH35-T-UVC-930-G12 35W Ceramic Metal Halide Lamp - G12 Base - 3000K - ANSI M130
The GE CMH35-T-UVC-930-G12 is a high-efficiency 35W Ceramic Metal Halide (CMH) lamp featuring a G12 bi-pin ceramic base and ANSI M130 ballast compatibility. This UVC (Ultra Violet Control) version delivers 6,400 lumens of warm 3000K white light with exceptional color rendering (90 CRI). Designed for retail display, accent lighting, and commercial downlighting applications, it offers superior color stability and 15,000-hour rated life.
⚠️ UV Radiation Warning - Enclosed Fixture Required
This lamp emits harmful UV radiation. It can cause serious skin burns and eye inflammation if the outer envelope is broken while the arc tube continues to operate.
- Must use in enclosed fixtures with adequate shielding
- Not for use where people remain for extended periods without UV protection
- Replace immediately if outer glass is damaged
- Consider self-extinguishing models for high-traffic areas

Recommended Ballasts - ANSI M130
Important: This 35W CMH requires ANSI M130 ballasts. Do not use M139 (70W) or M81 (39W probe start) ballasts.
GE Recommended Ballasts:
| Part Number | Model | Type | Voltage |
|---|---|---|---|
| 63044 | GEMH39-MSJ-MV | Electronic Multi-Volt | 120-277V |
| 63045 | GEMH39-MSF-MV | Electronic Multi-Volt (Fused) | 120-277V |
Note: Ballasts labeled "39W" typically support 35W-39W CMH lamps on M130 systems.
Compatible Third-Party Ballasts:
- Philips Advance Xitanium 35W CMH M130
- Osram PT-FIT 35/220-240 I (M130)
- Sylvania Quicktronic QTP2x35TC (M130)
Key Features & Benefits

Frequently Asked Questions
Is this a 35W or 70W lamp?
This is a 35W lamp (Order Code: CMH35-T). The "70W" listed in some specifications appears to be an error. It uses ANSI M130 ballasts (35W/39W system), not M139 (70W). The recommended ballasts (GEMH39) are 35W/39W rated.
What is the difference between G12 and G8.5 bases?
G12 has 12mm spacing between pins and is typically used for 35W-150W T6 tubular CMH lamps. G8.5 has 8.5mm spacing for 20W-70W TC (compact) lamps. They are physically different sizes and not interchangeable. This GE lamp uses the larger G12 base.
What does UVC mean in the part number?
UVC stands for "Ultra Violet Control." This version has enhanced UV-blocking properties in the outer glass envelope. However, it still emits UV radiation and must be used in enclosed fixtures. UVC provides additional safety but does not eliminate the enclosed fixture requirement.
Why does the cross reference list G8.5 lamps?
There appears to be a specification error in the original documentation. Philips CDM-TC and Osram HCI-TC typically use G8.5 bases, while this GE lamp uses G12. The electrical specifications are similar (both 35W, 3000K, M130), but the physical bases differ. Verify your fixture has a 12mm-spaced G12 socket before ordering.
