Did the globe take a couple of minutes to get to full brightness?
If it did, then it's a metal halide/ halogen globe.

Again if you arent growing plants it doesnt matter any ole light will do.
If you are growing plants then wattage will depend on what kind of plants.
Ive had a hood like that for a ten gallon with standard screw in sockets. If you dont have plants buy an eco smart LED low watt globe LED dont produce as much heat as a fluorescent and will save money in electric bill as they last longer dont use as much energy and are shatter proof.

Cool.
Then you can go two ways. Compact fluorescent one in each socket. Get 6700 K bulbs. Id get the highest watt your hood will allow. Should say somewhere on the hood. Im guessing between 10-15 watts for each bulb.
Or you could go LED screw in bulbs. Id recommend Cree LED as they have 90+CRI rating. With LED watts arent a measurement of effectiveness its all about Lumens. Find a bulb with the highest lumens your hood will allow. Again im guessing its going to be around 10-15 watt bulb. Each of these bulbs will cost between 4-7 dollars each and LED bulbs will last around 25000 hrs.
Or you could just replace your current hood with an led strip make sure it has mounting brackets or buy a glass cover to put it on. Depending on the plants you are growing will determine which led strip to buy. General rule of thumb for LED is 10-20 lumens per liter for low light plants. Which at 37 liters 10 gallons is 37× 20 = 740 lumens. Medium light plants is 20-40 lumens per liter and high demand plants with red in them more than 40 lumens/ liter. Most basic LED strips will be around 1500 lumens For around 40 bucks the more expensive ones 2500-4000 lumens. Or one could get two led bulBs in the 700-900 lumen range and have between 1400-1800 lumens which will grow most plants. Just make sure the bulb is 5000k-6500k and has a CRI rating of 90+

Hi I have another question, when a light has for exemple 10w but it says it does like 60w, what is the number of watt I should care about for the maximum of watt for the hood?

utahfish said:

Watts is kind of an archaic method for judging a lights growing power pay more attention to lumens but if judging the watts and the bulb says 10 watts like 60 then its generally the 60 watts.

utahfish said:

450 lumens isnt a lot, general rule is one wants 20-30 lumen per liter to grow plants at a K range between 5000-6500K and a CRI rating of at least 90 which i doubt the bulb provides.

There would be two of those on the hood so It would be more like 900 lummens and the light has 5000k or 5500k ( I don't remember exactly). I searched for like one hour last night and the other options I have are 3x more expensive. I dont think it is worth to pay 30$ on light for an aquarium that I paid 30$ everything included. I think I will ask an employee what is the CRI rating because it is not written.

I asked what is the CRI rating on the site and I think I will take the one I showed you if it higher than 80 because the one you are talking about has a CRI rating of 82 so I gess It is also good. Canadian Tire is also closer from where I live but thank you for your help.
