PHILIPS 901573 Master Color Elite Review

I use it for growing vegetables and flowers. But the lamp burns out earlier than specified. The spectrum is noticeably brighter for the first few weeks. Will have to order more.

Great Light! I use 30x30 in a tent. Plants love it for its size. I replaced a 50w x4 COB LED downlight with a total output of 200w (the listing says it's 800w). Thats much better! I've used it in the Hydro Crunch and it works great. Couldn't be happier. Will probably buy more.

manipulacion. Total outrage! Y además tendré Que pagar el envío de vuelta, del cual AMAZON no me reembolsará ni la mitad del costo de envío.

Works great so far. I almost finished my first grow with it. (3 weeks left) I use it in a 2x4x6 foot grow tent in a cheap mount. I won't know how well this works until I've harvested and measured the yield, but for now the plants are looking really good. This lamp produces less power than the 500 watt CF-8 T5 lamp I used previously.

The spectrum of this lamp is just beautiful. It replaces the 430+ watt T5 (which I have been using for many years) and the plants responded immediately and Expensive but not bad compared to replacing 8 T5 bulbs with better results and expected bulb life I am seriously considering CMH for paints.

This bulb (apparently used due to stains) is not even sold in the US. (ON BOX TO SAY NOT FOR SALE IN US) - and the word "COLOR" is spelled as "COLOR" as it is spelled in Europe. It says it all, and it doesn't say 4200K light. This is a counterfeit lamp or a lamp NOT sold in the US that was shipped to the US and is now being sold here.

Changing from 400w MH to 315w CMH has completely ruined my garden! All plans were delicate and stylish, with short internodes and a bushy plant structure. Now all branches have achieved four times the inter-node spacing in just a week with the 315W CMH! The idea that a 315CMH lamp can replace a 600W MH lamp is complete nonsense. I don't care what the numbers say, plants say it all! I have never seen so much stretch in my life until I switched to this 315 CMH lamp. This lamp strongly encourages…

I bought this pear 10 months ago. Since I've only had one return (due to my mistake) in the 7 years I've been a main Amazon member, I haven't tested if it works. I was PROBABLY sure that if Amazon sent me a defective product, they would fix it. Long story short I was just screwing in a lightbulb to grow some young marijuana plants and it was glowing and heating up to the max, I woke up this morning and crashed. When I first received it there were 2 small pieces of glass inside, but when it…
