SolisTek's Industry exclusive Double Ended Metal Halide is optimal for plant growth. The 4K MH-DE is a daylight full spectrum light and can be used from seed to flower. It is recommended to supplement with HPS during flower!

Solis Tek's Double Ended Bulbs (DE) feature low iron (Low-E) glass for enhanced UVA and UVB penetration to your plants for higher quality and yield! Solis Tek's special low iron glass allows for more UV spectrums to get to your plants and flowers. Low iron glass is composed of purified materials free from contaminants that make the glass extra clear. Usually glass has a green tint to it, these are impurities possibly from recycled materials. It has been proven that Low-E glass allows more UV light to pass through.

Why digital lighting? The Sun is high frequency. In order to make artificial light behave more like natural Sunlight it needs to be high frequency. Digital lighting makes for a higher quality of light that's good for all living things. This is only possible if you have the proper lamp and ballast combination.

The 4K Metal Halide is a full spectrum bulb that can be used for all stages of growth including propagation, vegetative, and flowering.

Specifically designed for high frequency electronic ballasts, it has a connection at each side of the lamp, removing the need for a frame wire inside the lamp. The absence of a frame wire eliminates any shadows in the beam. All Solis Tek Double Ended (DE) 1000w bulbs should be used with high frequency ballasts optimized for DE bulbs.

STK Lamps contain UVA-UVB and the upper portion of UVC. Exercise caution when working around any HID lamp that contains UV, always wear protective lenses.

  • Color Enhanced Full Balanced Spectrum

Solis Tek Metal Halide DE Lamp - 1000w 4K Questions & Answers

What's that gunk inside my lamp?

Have you ever opened a brand new box and wondered what the stuff was inside the lamps? Well you’re not alone, we get a lot of concerned customers thinking something might be wrong. The materials (gunk/goop) inside the inner envelope are actually the salts that comprise the gas chemistry provided by APL. When electricity flows through the arc tube, the excited salts give off their specific spectrum.

These salts will burn off after a seasoning/break in period of ~100 hours. After this point your lamp will be operating at it's optimal spectrum. A slight amount of pulsating in the lamp is common until the lamp is fully seasoned. Solis-Tek is the only company that does not pre-burn in their lamps. This way you can truly tell you have a brand new lamp. It also provides you more operation lamp life!
