DLI is the most important piece of growing cannabis. This meter provides precision DLI as well as led intensity or PPFD. A little pricey but the instrument is 2nd to none. I use it throughout my grow. ### ⭐⭐⭐⭐⭐ Reliable *by B***K on October 14, 2025* Good product. But don't get it wet ### ⭐⭐⭐⭐⭐ Can't beat the accuracy and reliability of Apogee products *by L***Y on October 21, 2022* If I had to force a complaint I'd say I wish I didn't have to remove 2 screws to access the USB-C port, but I have no doubt it's concealed where it is for a reason, and it's not much of an inconvenience at all. Otherwise it's all positive marks for the DLI-600. The universal thread is a great idea, I picked up an inexpensive, telescoping tripod/wand to use for quick and long term readings. Compared these readings with a 2 year old MQ-510 and they're nearly identical. Easy to access the files via the included USB-C cable on my laptop. You get what you pay for and I have no doubt this DLI-600 will be taking accurate readings for years to come. No more burning, or under lighting my plants. Keep up the good work, Dr. Bruce. ## Frequently Bought Together - Apogee Instruments DLI-500 PAR, Daily Light Integral, and Photoperiod Meter - Full-Spectrum 400-700 nm Light Measurement Tool for Plants & Agriculture - AC Infinity UIS Splitter Hub, 4-Port Adapter Dongle, Connector Cable Cord to Share UIS Programming for LED Grow Lights, EC Motor Fans, and Humidifiers - AC Infinity Self-Watering Fabric Pot Base, 4-Pack Auto-Irrigation Water Delivery System with Reservoir Meter, Elevated Plant Saucers for Use in Indoor Grow Tents, Greenhouses, and Outdoor Gardens --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/415217512-apogee-instruments-dli-500-par-daily-light-integral-and-photoperiod](https://www.desertcart.vn/products/415217512-apogee-instruments-dli-500-par-daily-light-integral-and-photoperiod) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-09*
