I bought a 75w UFO looking grow light from Ali-express a few years back. Used to to grow chillis from seeds in a cupboard. Worked very well, never had so many plants successfully grow. Doesn't look like the one I got is still available though.

 

 

Throw a picture of it up perhaps?

 

 

Similar to this one.

Yes. https://www.sanlight.com/en/ are professional lights. I personally use two models for chili growing since 4 years and can fully recommend them. The fanless lights aren't by far not as 'pinky' as the chinese ones and very efficient. Not cheap but worth it's price.

 

 

Finally - it looks like someone's selling grow lights with an image of something that looks like a chilli seedling:

 

 

What's "spannabis"?

I have got a bottle of Death Nectar hot sauce I bought in NOLA. Had to sign a waiver before they would let me taste it.

 

 

 

O M * G it is hot. I could save you growing chillies and send you a teaspoonful in a pottle - that would be enough for about a year I reckon!!

For the narrow spectrum LEDs, I would only recommend buying them from a reputable brand such as Philips, I've heard good things about sanlight but I haven't got any experience with them myself.

 

 

 

If you don’t mind buying locally I would recommend easygrow https://www.easygrow.co.nz/93-led-grow-lights

 

 

 

The narrow spectrum LEDs are quite good and I know of a few commercial growers that use them.

 

The main problem with them for a hobbyist is that they are generally tailored to a specific type of plant and growing phase, so unless you want to change them every few weeks/months, I would recommend using a full spectrum LED. And as a general rule of thumb, don't trust any cheap narrow spectrum LEDs.

 

 

 

If you live in a cooler climate, the HPS or fluorescent lamps may have an advantage due to the amount of heat they put off.

On a side note, if you do every plan on controlling main powered devices.

 

Use something like this Relay Box from AutoGrow. you just need to give it 24vDC it activate the relay and its a-lot safer than building something yourself.

Easygrow have a lot of fairly expensive grow lights. My rubbish one from ebay was $10, waste of money, but they have a version that is probably similar but better quality for $60.

My concern with local retailers like Easygrow is that there are no reviews of the products. They look very similar to lights available through AliExpress, and even where you can research the performance of the type of LED used, there is no guarantee that the supply chain has provided them with what they think they are selling. Sticking with HPS/MH lighting seems to be the safest option for getting the desired performance from lights. I've seen many comparisons with cheap LEDs, and they have performed poorly in comparison.

 

I'll need to run the numbers and determine if I opt for a more expensive LED, or go for the higher power usage options.
