How far away from my plants should this grow light be?

 

How to use a distance guide

Distance matters more if this will be your plants only light source (which is what the following distances are based on). Keep in mind different plants have different light requirements, so start at the higher / further away of the distance range and adjust closer or further away depending on the plants light requirements. Closer if growth is slow or leggy, further away if leaves look to be getting too much light.

Distance guide (36 watt)

1 metre to 1.5 metres away for seedlings and cuttings (coverage 27 square feet / 2.5 square metres)

75cms to 1 metre distance for foliage growth (coverage 12 square feet / 1.1 square metres)

45cm to 75cms for blooming and fruit production (coverage of 3 square feet or 0.3 square metres)


10, 15, 24 watt or 36 watt?



36 WATT For a bigger collection, to cover a larger area, to mount higher up / further away for wider coverage, for a small greenhouse, for a large grow tent, or for a collection of plants that prefer very bright or direct light (including succulents and cacti), go for the 36 watt. Also for small trees and fruit production for larger, established plants. Coverage area is larger and output more intense, so it can also go higher up / further away than lower wattage bulbs. The extra bank of lights in the centre compared to the 24 watt offers higher light intensity for up to small greenhouses or larger grow tents.


24 WATT For a medium-size indoor plant collection or if you want two lights (which avoids plants growing towards one direction only), choose one or two of the 24 watt. Watch the video below which shows the 24 watt. One or two 24 watts are the most popular choice for most indoor plant hobbyists (you can always start with one and get a second later). 


15 WATT For smaller collections, for using over a prop tank, for a tray of seedlings or cuttings, for lighting up individual plant shelves, for use inside small grow tents and for baby plants and smaller-growing plants like African Violets, one or two of the 15 watt or 10 watt are ideal, with the 15 watt being the more popular of the two.


10 WATT The 10 watt is the better choice when you need to mount the light closer to plants (such as over the top to cover one tray of seedlings or to light up one plant shelf), or for a smaller number of plants. The 10 watt also fits the biggest range of lamps. It has the same standard E27 screw-in fitting as all sizes, but is not as wide or long as the 15 watt, so less conspicuous if you want a more aesthetic solution than can be hidden within most shades. 


What to put your grow light in



Since Sansi have a standard NZ E27 screw-in fitting, you'll find they are compatible with most desk lamps, floor lamps and pendant cord kits. However, grow lights have wider and longer bulbs than standard indoor lightbulbs so if you want a shade, look for one that's longer / wider than standard. As Sansi grow lights are directional, a shade isn't required (see the video below showing the beam without a shade).


Although LED grow lights run cooler so don't have the same risk of burning your plants, they still need some airflow around the bulb, so I'd allow a good 3cms or so extra on all sides, meaning you may need either no shade (recommended), or a wider than usual shade in an area with good airflow so things don't get too hot which risks burning out your bulb.


Have a watch of the video below for an idea of size as the 24 watt (in the video) and 36 watt are a similar larger size whereas the 15 watt and 10 watt are small enough to fit with plenty of room around them in most lamps with shades. The 10 watt is a similar size to a standard round light bulb.


I suggest buying your bulb before your lamp and taking your bulb shopping with you to check fit in-store - or just purchase your lamp from a store who is relaxed about change of mind returns if you find it doesn't fit - and keep your receipt!


If you prefer to hang it either from the ceiling or from an L bracket on the wall, I also have these pendant cord kits available in 4 colours that have E27 fittings and are rated for up to 60 watt bulbs so are compatible with the Sansi bulbs.


To get a better idea of the bulb size, brightness and distance from plants, have a watch of this video which uses the 24 watt size:


 

Included: Bulb in box as shown. Pendant cords or other accessories shown are not included (available separately). 


Warranty: Sansi says their LEDs are rated to run for up to 50,000 hours in theory, BUT that doesn't account for conditions in our homes. Factors like heat, moisture, airflow and more can have a big impact on how long a bulb will last.

As you can tell from the price, Sansi are great value-for-money for an entry-level solution to boost light levels for houseplants grown indoors, but are not a high-end, premium solution. 

In my own use at home I find I get 1 to 3 years per Sansi bulb and at that stage they usually still work, but slowly become dimmer over time (called lumen degradation, normal for all LEDs). 

I provide a 6 month warranty on electrical items I sell (including Sansi bulbs), which covers manufacturing faults and defects. It doesn't cover wear and tear, accidents or faults caused by conditions. The consumer guarantees act also applies to home use.

Evie and Maddox
Format: Kindle
Please check trigger warnings before diving in. This book was an emotional rollercoaster in the best way. Tuesday James did an incredible job crafting a story that flowed effortlessly while packing a serious emotional punch. The found family dynamic hit me right in the feels, and the backstories? Heart-wrenching. Evie and Maddox have been through so much—it’s impossible not to root for them. Their healing journey isn’t easy, but the way they lean on each other makes every struggle worth it. The side characters were fantastic, bringing warmth, friendship, and that cozy found-family vibe. And Evie’s twin boys? Absolutely adored them. Their bond with Maddox was heart-melting. Speaking of Maddox—his growth was chef’s kiss. He starts off as a broken man, using anger as a shield, but Evie cracks through that armor, bringing light back into his life. Not gonna lie, he irked me around the halfway mark, but once his backstory unfolds, you get it. Was he right? No. But he’s trying, learning, and making up for past mistakes, and I love that. Also, that man and his filthy mouth? Devoured this book the same way he devoured Evie. And Evie? Absolute powerhouse. She’s been through hell but never let her storm touch her babies. Watching her be the best mom while fighting for her own happiness was everything. I’m beyond excited for the next book because if this one is anything to go by, it’s going to be so good. What to Expect: ❤️ Grumpy x Sunshine 🖤Hurt/Comfort ❤️ "Pretty girl" 🖤 Height Difference ❤️ Plus-Size FMC 🖤Single Mom on the Run ❤️ FMC with Physical Scars 🖤Trauma ❤️ Banter 🖤MMC in Glasses ❤️ Who did this to you? 🖤Dark Small-Town Romance ❤️ Found Family Thank you to Tuesday James, the author, and the Author Agency team for the ARC opportunity!

Obsessed. Destroyed. Healed. Tuesday James’ debut is everything.
Format: Kindle
4.5 These Jagged Edges by Tuesday James is the debut that grabs your heart, gives it a squeeze, and then stitches it back together, one broken piece at a time. Meet Evie: fierce, no-nonsense, and a single mom who’s escaped her traumatic past but still carries the weight of it. Enter Maddox Wilder: broody, broken, emotionally unavailable—everything Evie should avoid. She’s everything he thinks he can’t have. But of course, they can’t stay away. This book? Pure emotional chaos—and I am HERE for it. Evie’s journey as a mother, survivor, and woman finding her way back to love? Breathtaking. And Maddox? Oh, honey. He’s the broody, big-hearted hero that makes you scream, "Let me love you!" The chemistry? Electric. The tension? Off. The. Charts. The spice? Don’t even get me started. The side characters? OBSESSED. Mercy is the flirty golden retriever we all need, Vic will steal your heart, and the twins? Pure joy. This book isn’t just a romance; it’s a found family story that will make you laugh, cry, and want to hug every single character. Tuesday, please don’t make me wait too long for Lou or Mercy's stories. I’m begging you. The writing? Lyrical, gut-punching, and beautifully raw. Every single moment will hit you. If you love grumpy-sunshine, second chances, and emotional healing that’s messy, imperfect, and oh-so-satisfying, this is a must-read. Read it. Cry. Hug your loved ones. Then DM me so we can scream about Maddox Wilder together.

Awesome story but…
Format: Kindle
The first half of the book needs a lot of editing. Normally I wouldn’t mind but there were a lot of mistakes. If you take that out of the equation, it’s a solid 4. But this as it is for me is a 3.5 The story is somewhat unique and it brought emotions in the second part.

Dark Romance - Small Town - Suspense - Enemies to Lovers
Format: Kindle
I'm soo glad I read this book. Maddox plays the big tough man with a hard exterior wall. Meanwhile, Evie, who was always stronger than she thought, broke down all his walls. Like true enemies to lovers, Maddox and Evie got under each other's skin to the point they collided and explosions went off...literally. The banter in this book, yeah, chef's kiss. This book has offers a lot. Each character has their own flair to them. Each one showed a level of growth and depth. Sometimes when I read certain books, it feels like I'm just getting the shell of what could have been. Not this one. Tuesday brought the fire. Every human emotion possible I felt while reading this book. I screamed, laughed, cussed, rolled my eyes, and sobbed. Seriously, for all those who love dark romance books with a plot and an excellent characters, this one's for you. Oh - the SPICE be SPICING.

Cute small town and found family.
Format: Kindle
Evie and Maddox’s story was so sweet. Obviously there were many parts that I wouldn’t call sweet, but overall it was a cute love story. I thought the author did a great job with the Grumpy X Sunshine trope. Cause Maddox is def a big ol grumpy. The found family trope is so strong in this book and I think that might be my fav part! Were there a few parts that Maddox made me realllllll upset? Ohh yes absolutely. In reality tho, that almost made him more believable. In no way am I giving an excuse for how he used her trauma against her. Cause that was absolute trash. But I did enjoy him spending the rest of the book attempting to make up for it. He could’ve groveled more tho lol. I absolutely loved the twins relationship with each character in this book. I think they were so important to the story and added that extra bit. How they protected their mama so fiercely was everything. It felt like some of these scenes were just thrown together. Meaning, some details were just dropped in but no other context with it. Like tidbits of info that didn’t really go with any part. Other scenes were clearly thought out with so much detail. The storyline was really interesting. I enjoyed that the FMC/MMC were able to show their trauma and grow and heal from it. I loved how the author showed the MC’s were able to live outside of their trauma and be who they are, not who the trauma made them. I think this was a very good debut novel depicting just how common the cycle of abuse can be, but even more so how you can break out of it. Not all homes are filled with love and understanding, but Evie was bound and determined to have that in her home.
