Help. I would like to get opinions on buying an older light. The light is an HLG550 eco with a meanwell 480 driver. 3k on the light color. I need this for flower. Will it work? I have the opportunity to purchase four of them. Please advice needed. ![s-l1600](https://global.discourse-cdn.com/growingmarijuana/original/4X/3/1/6/31697fd3aa9f15283cb9439c0eeefefe91312414.jpeg) Thanks for your time. ---

Yes, that is a good light, any HLG is good. If they are reasonably priced, I’d buy all 4, as long as they don’t have a ton of hours on them. ---

I am.told they are a year old, not much to go on there. They are $150 a peice, is this a fair price? I sure take the advice. ---

@Growdoc will the 3k work for flower? ---

Yes, that’s toward the red end, that’s what you want for flower, 2700-3000. ---

And 150 for HLG sounds like a deal! I’d buy them all. ---

@Growdoc Thanks for the input. I took the advice and got all 4 of them. How much light can i pack in a grow space before it is to much? Is this possible? ---

I am super excited about getting the lights. Pumped I tell ya. I have been dragging my girls around in the sun for a couple months. My buds are small because of not enough light. I live in the woods so it’s lots of shade. You can see my grow here. > [@The Grow journal begins October 2025](https://ilgmforum.com/t/the-grow-journal-begins-october-2025/120628): > > It has been a while since i have been able to stop by. A needed order and a lot more time on my hands (retired) i am able to write a journal. I am very excited about seeing everyones growing experiences, they only make mine better. Thanks to all of ya! My need for smoke averages 2 oz a week for our household. It is legal where i live yet very expensive. 225 an oz to get good enough wwed to do me. So, i grow. Here is where i stand as of now. ILGM seeds coming next week for my next grow. … My poor ass has been a saving for months expecting to spend (lots) on a good light. For me I was expecting to spend around a grand on a good light. Now, I am here right upon winter with 15 girls outside and half of them are in flower due to the time of year. I felt kinda like winter might force me to pull the girls in and no light at that point. Soooo When I ran across 4 of these hlgs 550 v2 and now I see they are for a 4x5 flower coverage, shit that is enough for a 10x12 tent. I have gotten very excited. And I got them 150$ a piece. I was so excited I couldn’t get anything done all day. Hookups like that are very much appreciated. And perfect timing.for me. All I can imagine now is huge buds. Lol ---

I love the mountains, i have seen those over that way, they are beautiful. After a few years of planning a move, recently i have .oved to a new property. Never inhabited before. No light in here, it is all woods. I was gonna cut me a space for light and plant a garden as well as the girls. But, after i got here i feel in love with the trees, all huge oak with a few pine. I just can not bring myself to cut trees. This brought me to the deciding indoors, in which i just ordered some used lights, i hope they are okay ---

You got a pretty good deal. Two of these at 40% power would be more than enough for your grow space. ---

Thank-you for your input. I was worried about them being an older product, used. I have been saving for a light for months, a good one cost a bunch. It was price that got me on this one. After i have made the purchase i am learning more about the lights. I have gotten excited. I can expand my grow space. This gives me options i have not had in the past. My past experience has lead me to believe, light is the most important piece of the process, its a place that should not be second rate if at all possible. Wanna skimp, get a cheap tent, bucket to grow in, anything, just don’t skimp in the lights. I feel these lights will stand up and do the job. bigtime. So i think ---

@Growdoc @kellydans @dbrn32 I want to Thank you guys for the advice on the old used lights. In the past i have followed advice from ILGM and never regret it. This ti.e around i was advised to purchase all that i could. Advised me.thst it was a good deal. At least it is how i took.it. i wanna give a big shout out to grow @Growdoc for suggesting to buy them all. Damn u iu were right. I really had no idea what i was purchasing. I did purchase all 4 in wbich they had. Took mmm two weeks to get mmm to me. Honestly i thought i purchased a scam because it was so cheap and took so long to get here. With no communication. All in all, when tbey got here they are worth way more than i ever expected i could purchase. I surely didn’t have the knowledge to be confident enough to buy them all. Or even one for that matter. I am so thankful for the advice to buy all. You guys and gals are bad ass! Thanks! I hope you all have a kick ass harvest!
