Understanding Streamlight’s TLR Naming System
The Streamlight TLR family follows consistent naming patterns based on official product specs. Base numbers indicate size and form factor: TLR-1 for full-size pistols, TLR-7 for compact guns, TLR-8 for compact models with integrated lasers.
Letter suffixes specify key features. “X” denotes multi-fuel capability, accepting both SL-B9 rechargeable and CR123A disposable batteries. “HL-X” adds high lumens output with multi-fuel support and often includes a USB-rechargeable SL-B9 battery. “Sub” indicates micro-compact mounting for subcompacts. “G” signifies a green laser.
The original TLR-1 produced 300 lumens. TLR-1 HL upgraded to 1,000 lumens. TLR-1 HL-X increased to 1,500 lumens with front paddle battery access. The TLR-7 series advanced from the TLR-7A to the multi-fuel TLR-7X at around 500 lumens, then to the TLR-7 HL-X delivering 1,000 lumens in a compact package.
TLR-1 Family Complete Breakdown
The TLR-1 HL-X dominates full-size pistol applications. With SL-B9 batteries, it delivers 1,500 lumens and 20,000 candela. CR123A batteries maintain 1,500 lumens with comparable candela performance.
Front paddle battery access allows changes without removing the light from the rail. Runtime hits about 1.5 hours on SL-B9 high mode and 2.5+ hours on CR123A. It’s priced at more or less $200.
Major holster makers like PHLster, Safariland, and Tier 1 Concealed widely support the TLR-1 HL-X with compatible options.
The TLR-1 HL provides 1,000 lumens on CR123A without multi-fuel.
The TLR-1 HP-X outputs 1,300 lumens and 77,000 candela for extreme throw in specialized distance roles.
TLR-7 Family: Compact Carry Champions
The TLR-7X hits the sweet spot for carry guns. Both SL-B9 and CR123A batteries deliver 500 lumens with 5,000 candela. Multi-fuel flexibility and 2.58-inch length provide excellent value at $165 – $170. Runtime: 1.5 hours CR123A, 1 hour SL-B9.
The TLR-7 series offers high-output options like TLR-7A FLEX at up to 500 lumens standard, with some variants reaching enhanced performance around 1,000 lumens peak in strobe or specific modes. Compact 2.58-inch designs balance throw and runtime effectively.
TLR-7 Sub variants fit micro-compacts with platform-specific mounting. Performance: 500 lumens and 5,000 candela with SL-B9. Verify pistol compatibility and holster availability first.
TLR-8 Family: Adding Laser Capability
The TLR-8X adds a red or green laser to the TLR-7X’s 500-lumen platform. Programmable modes offer light only, laser only, or both. Dimensions match TLR-7X closely at around 2.58 inches.
The TLR-8 HL-X combines 1,000 lumens and 22,000 candela with laser on SL-B9 (500 lumens/11,000 candela on CR123A).
Lasers excel in low-light scenarios and unconventional positions but fade in daylight. Laser-only mode extends the runtime significantly to around 10 hours. Only add if you’ll train properly.
Direct Model Comparisons
TLR-1 HL-X vs TLR-7 HL-X
Performance: TLR-1 HL-X produces 1,500 lumens versus TLR-7 HL-X’s 1,000—but candela reverses expectations. TLR-1 HL-X delivers 20,000 candela while TLR-7 HL-X concentrates to 22,000, throwing farther despite lower lumens.
Size and weight: 3.45 inches and 4.94-5.3 ounces for TLR-1 HL-X versus 2.88 inches and lighter weight for TLR-7 HL-X. Runtime favors full-size at 1-1.5 hours versus 30-45 minutes.
Choose TLR-1 HL-X for full-size duty pistols needing maximum runtime. Choose TLR-7 HL-X for compact carry requiring better concealment with a tighter beam.
TLR-7X vs TLR-7 HL-X
Output jumps from 500 lumens/5,000 candela on TLR-7X to 1,000 lumens/22,000 candela on TLR-7 HL-X with SL-B9. Candela boosts dramatically for superior throw.
For daily concealed carry at typical defensive distances, TLR-7X’s 500 lumens suffice while saving money. Duty or competition justifies TLR-7 HL-X’s superior throw beyond 30 yards.
Holster Compatibility Deep Dive
Purchasing lights before verifying holster availability creates expensive problems. Light-bearing holsters cost $80 – $150 versus $40 – $60 standard, with custom molding requiring 4-8 weeks.
TLR-1 family offers extensive holster options from PHLster, Tier 1 Concealed, Safariland, and Dark Star Gear. Newer HL-X variants may not fit older TLR-1 HL molds due to dimensional changes.
TLR-7 family provides strong support nearing TLR-1 levels from PHLster, Vedder, and Werkz with solid AIWB selection. TLR-7, TLR-7A, and TLR-7X often share holsters, but TLR-7 HL-X and Sub require specific molds.
Before buying, verify three-plus manufacturers make holsters for your specific pistol-light combo. Check lead times and budget $80 – $150 additional. Missing holster listings or only universal options indicate problems.
Real-World Use Case Recommendations
- Home Defense: Choose TLR-1 HL-X for maximum 1,500-lumen output, ensuring positive identification. Runtime suits brief activations, and rechargeable batteries simplify monthly checks. Alternative TLR-7 HL-X works for compact frames with adequate 1,000 lumens.
- Concealed Carry: TLR-7X delivers optimal size-to-output balance at 500 lumens. Excellent holster availability and multi-fuel flexibility justify the price. Upgrade to TLR-7 HL-X if your carry gun sees duty use, accepting ~0.3-inch length increase for 22,000 candela. Micro-compacts need platform-specific TLR-7 Sub variants after verifying compatibility.
- Duty Use: TLR-1 HL-X provides maximum reliability with an extensive holster ecosystem critical for level-retention systems. Rechargeable batteries reduce training costs. Alternative TLR-7 HL-X suits compact duty pistols with superior 22,000 candela throw.
Battery Strategy and Power Management
Multi-fuel capability means one light accepts both SL-B9 rechargeable and CR123A disposables. Maximum output like 1,500 lumens on TLR-1 HL-X requires SL-B9, while CR123A provides reliable backup power at matching or sustained high levels. Use rechargeables for training and disposables for emergencies.
SL-B9 batteries deliver 850mAh at 3.7V with built-in USB-C charging. Full charge takes 2.5 hours, reaching up to 500 cycles before degradation. Cost runs $20 – $25 versus $3 – $5 for CR123A, breaking even after several cycles.
CR123A advantages include a 10-year shelf life and cold-weather performance below 20°F, where rechargeables struggle. Reserve these for emergency backup and extreme conditions.
Home defense lights need battery replacement every 6-12 months with monthly function tests. Daily carry lights benefit from brief activation when holstering plus weekly recharging. Duty use requires daily checks and a recharge after every shift.
Common Buyer Mistakes and How to Avoid Them
- Wrong Size Selection: Match the light size to the pistol category. Full-size pistols like the Glock 17 need the TLR-1 HL-X. Compact pistols like the Glock 19 work with TLR-7X or TLR-7 HL-X. Micro-compacts require specific TLR-7 sub-variants.
- Skipping Holster Verification: Research holsters before buying lights. Verify three-plus manufacturers support your combination and budget $80 – $150 additional for quality light-bearing holsters.
- Buying Outdated Models: Focus on current X-series and HL-X variants. Original TLR-1 at 300 lumens often costs less than TLR-7X’s 500 lumens. Only buy older models when saving significantly.
- Ignoring Multi-Fuel Benefits: X-series capability saves hundreds annually in training costs. The premium pays back within 6-12 months of regular practice.
- Adding Unused Lasers: Only buy TLR-8 variants if you’ll actually train with lasers. Otherwise, light-only TLR-7 models keep things simpler and cheaper.
Maintenance and Authorized Purchasing
Daily checks for carry guns involve quick visual inspection and brief activation. Weekly maintenance includes checking O-rings and cleaning battery contacts with isopropyl alcohol. Follow manufacturer instructions for deep cleaning without full user disassembly.
Flickering usually indicates dirty battery contacts—clean with isopropyl alcohol. Dim output suggests battery issues or thermal protection. Ensure vents remain unobstructed and allow cooling between uses.
